Born & Birth stories

This is the last week of your first trimester and your baby weighs 14 to 20 grams. The crown-to-rump length of your growing baby is 2.6 to 3.1 inches. Your baby is now about the size of a peach. Fetal growth is amazing from now through about the 24th week of pregnancy.

At this point of your pregnancy, there is a steady flow of pregnancy hormones in your bloodstream. Your body will adjust to the changes and morning sickness might stop and other early symptoms will begin to ease. Because the second trimester is approaching, feelings of anxiety or nervousness may also diminish. You have probably gained some weight by now. You are losing your waist and your clothing is probably fitting snugly.

There is a milky membrane that surrounds your baby. It is pierced by the umbilical cord and is made up of two layers, which are fused together. Your placenta provides most of the nutrients and oxygen that your baby needs. By this week, the placenta is well formed and ready to take over hormone manufacture from your ovaries. The placenta will produce progesterone and estriol. These hormones will be crucial in the maintenance of your pregnancy. Tissue that will form your baby's bones is being laid down, especially around the head and limbs. The nose and chin are becoming more prominent. Your baby's eyelids meet and fuse together and they will not open again for nearly four months. The eyes started out on the side of your baby's head and they are now moving closer together on the face. The ears come to lie in their normal position on the sides of the head. If examined outside of the womb, you will be able to distinguish male from female at this time.

The sockets for all twenty teeth are formed in the gums, and vocal cords are beginning to form.

Tanya don't believe anything...,Chinese calendar said boy for my daughter all old wive tales

tanyaschmalz - 1.4 hours ago
Girl from the baking soda test and the Chinese predictor says girl. Damn it. I'll get the gendermaker in a couple weeks. I knew it was a girl but I didn't want 2 believe it.

Mom~of~2 - 1.8 hours ago
1 teaspoon in a cup pee in the cup if it fizzes then it's a boy...if it's flat then it's a girl

tanyaschmalz - 2.2 hours ago
I can't do the test cause I feel dehydrated so it'll be wrong. What is it? Fizz boy or girl?

Mom~of~2 - 3.6 hours ago
Good luck Mommynicole! I'm wishing you have a healthy baby regardless of the gender! Can't wait to find out what your having :) I go for my u/s March 20! Can't wait!!!!!!

mommynicole81 - 4.5 hours ago

Company is gone!!! My house especially kitchen is a disaster dreading the thought of cleaning all those dishes.....I've been feeling tired lately as well nausea hits me alot too

Hope - 5.1 hours ago
This baking soda test had me intrigued. I googled it and found one site that polled people who knew what gender they were having (from u/s) and asked them to try the test and say if it was accurate. The results were over 70% accurate. I tried it just for fun and got pretty much no fizz, so maybe a girl??? We never find out - I like to wait until delivery. A girl would be great tho. We have six kids - the oldest and youngest are girls and four boys in the middle. So lots of testosterone in the house LOL! Of course, we are just praying for a healthy baby.

Momof2 my doc said my thyroid was fine. I guess I just need to make myself get up and go. I believe when I get some type of appetite back, I will be better. JH is could very well be your baby. I feel mine by my belly button too. I will be 15 weeks in 4 days, so I assume my uterus must moved up some more since I had my ultrasound at 12 +6 days.

JH - 7.4 hours ago
I just had another weird feeling in my abs. I was folding a shirt so nothing strenuous. At first, catching me off-guard, I thought i pulled something. But then I realized I didn't have pain. There is no way gas can feel like that. But it was up kinda high. Right around belly button height. Any ideas?

tanyaschmalz - 7.7 hours ago
If I understand right the morning pee probably is 2 acidic or something. Better 2 use pee from later in the day.

Mom~of~2 - 8.6 hours ago
Ladies if your tired ask the doctor to check your thyroid mommyNicole any pee is good I heard doesn't have to be morning :). My company just came ttyl

Nattashia - 10.9 hours ago
Hi girls! Ive been feeling really tired these last couple weeks, I was really hoping that it would start to disapear but its not yet. I cant seem to want to get out of bed in the morning and once im up I just pass out on the couch! I think its the fact that I have a 8yr old and a 5 yr old as well as running a home daycare watching 2 or 3 more kids.... I also start a new job at a nursing home next week! Im going to be so busy and overworked that I hope the tiredness goes away and I start having more energy and the new job doesnt stress me out to much. Ive finally gotten my appetite back a little, im able to eat more things... as I type Im munching on a chili & cheese baked potatoe YUM YUM now if only I could fight off my 5 yr old who wants it. Anyone else having this problems? it seems that everytime I get food out to eat my daughter bugs n bugs to eat it and I end up with nothing :( it really bugs me because I know I need to be eating something and my tummy is talking to me but its hard to say no to the kids when their saying their hungry to ( even tho they just ate and didnt even finish it all bc ' Im full mommy') AHHH lol.

mommynicole81 - 12.1 hours ago
Mom of 2 I am now in week 14 but the baking soda in pee is it suppose to be morning pee or anybody else know cause i am just in the mood to try that before my 4D ultrasound on the 26 :)

evansbabyg - 13 hours ago
I ate two grilled cheese and went to sleep and just woke up with a headache out of this world. I guess they went to church without me as it does not seem that no one is in the house. I still have fatigue like Iam in week 6-8. Does anyway else feel this way and how are you overcomming it? I think because I get no sleep at night that maybe I feel I need to sleep during the day to make up. Anyway, Tanya DH says mine sit up high too.

tanyaschmalz - 13 hours ago
Evans, no news yet and no autopsy scheduled yet. Lame. I am tired today. I wanted a specific sandwich from a hole in the wall deli yesterday afternoon. I was dying for it even though I never had it before. I went and got it and it was so disappointing. It looked so good.

tiffanygannutz - 13.4 hours ago
Evans- have I had people at work tell me that this past week because I've had to go up there is my reg. clothes and not uniform to get my FMLA paperwork filled out and sent in. I am also finding baby up higher too since I have felt like I've popped. Hubby hasn't said much because he knows I feel like a big ol' fat cow.

evansbabyg - 16 hours ago
Good Morning Ladies! My husband looked at me this morning and said you are really starting to pop out...lol...Iam surprised too since I do not eat as much and lost so much weight at first. He loved telling his friends about the baby and the only things I would eat....heck he even told them about my constipation problem...lol..he does not have a filter sometimes...anyway I hope all is well and Momof2 you did what was needed when you got the car. Tanya I still do not see what Whitney die of...did you? Lord help her kids and family during this time. xxxxxxxx

tanyaschmalz - 1 days ago
I really wish they'd post how Whitney Houston died. So frustrating 2 hear she's dead and have a million ideas of what could've happened.

evansbabyg - 1 days ago
Just able to lay down after my bath. I finally told DH to start telling them that it was time to go...i really was so sleepy and wore out! I pray everyone has a wonderful night.

Mom~of~2 - 1 days ago
evansbaby I feel ya! My DH is not home from work yet and I've been without a car all day! I need to go shop and get things ready for tomorrow it's almost 9 pm here! So sad for Whitney Houston....RIP....She will never be forgotten I loved her music when she first started her career!

evansbabyg - 1 days ago

evansbabyg - 1 days ago

The baby was moving alot like she wanted to get out and play...ha..ha! I ate food like never before and my hubby still got company so Iam entertaining as their wife have came over since Iam at home now...urghhh...pls people go home...

cowgirlemily - 1 days ago
The site isn't completely fixed. I'm on the list and my profile isn't completely there. It is getting better tho! I remember my doc asking last time about birth control. So I tried to tell everyone the big news.... My aunt (who had 1 mc and unable to have more children after that) hasn't been cooperating! I tried to take a chocolate cake over to my Grandparents house last night and surprise everyone- she was busy. Today, I called her to see if we could go over.. no she doesn't feel well. Maybe tomorrow if she feels better... but I was planning on going and doing other stuff. UGH! She is sooooo difficult for everything!

tiffanygannutz - 1 days ago
I will be going back on the pill. I was switched to a different one than I had before I had the mirena put in. I had problems with it and had been bleeding with the mirena on and off for over 6 months and had it taken out. My doc has never pushed any type of birth control on me. When a certain type of birth control and brand works for me I have to stay on that one because if it gets changed my whole system gets messed up and I have to go off the birth control for a while.

Mom~of~2 - 1 days ago
Welcome back Nikki12

Mom~of~2 - 1 days ago
Natashia thanks for the info! Every time I think about getting that I have a debate of all the pro's and con's IDK I'm so confused. My DH doesn't even want me getting that but I'm telling him that I can't take the pressure of having any more babies this close in age after this one is born! I am kind of scared also to get the IUD because my cousin had one in and she got pregnant which put her pregnancy and her baby high risk! Thankfully her baby was ok but I believe he has some issues right now. They said they couldn't remove the IUD without hurting the baby in some sort of way and she was too far along in her pregnancy to take it out. So they left it in there until the baby was born! So again I end up thinking about birth control IDK again i'm really iffy..Thanks for listening! lol :)

Nattashia - 1 days ago
momof2- not everyones period totally disapear! I still had mine during the 4 yrs mine was in it was just a little lighter and shorter

Nattashia - 1 days ago
momof2, after my first child I had an iud (mirena) put in and I loved it while it was in my period was getting lighter if really any at all some months. My husband said he never felt it when we got intimate, really I LOVED it. Thank god I have benefits tho bc it was very expensive ($500 canadian). I had it in about 4 yrs unitl DH and I decided we wanted another baby. It took me roughly 8 months to get pregnant after it was removed. Im thinking on what I want to do after I have this baby, Im not 100% sure if I want another baby or not in a couple years. I dont want to get my tubes tied and then years down the road want another one and have all kinds of stress to go thru just to have another baby, but what if I get an IUD and choose that we never want to have a baby again and have to have a surgery to get them tied??

Mom~of~2 - 1 days ago
didgeridoo thanks for the info on the IUD....but you mentioned something that I really don't think I will go for anymore; which is the fact that I won't get a period!! AHHH!! I honestly miss my periods I feel relieved and my bloating goes away when I get my period....Evansbaby I don't know about your nephew coming to live with you is such a good idea only because you have 3 boys of your own and then a lo on the way...You will be a busy mom and then to have to take care of him as well you will be a super busy mom lol I know you love your nephew because I would be so stressed and feel like I have to take him! (That's the type of person I am though)I would just be honest and be like sorry won't be able to! That's just my opinion though! :) Good luck with whatever happens! (HUGGS)

nikkib12 - 1 days ago
Hey ladies its Nikkib11 , i had to make a new profile because I couldn't log onto my old one :P

evansbabyg - 1 days ago
Didgeridoo that is a good angle to approach it and that is what Iam going to use...lol...Iam so glad I joined this site!

evansbabyg - 1 days ago
Thx Didgeridoo. I talked to my daddy and he is upset at the fact that my sister is not letting him go to college where she stays. She is in LA and her twins stay with their dad after she got a divorce to finish their high school at the same school. The point is that she did not have the boys for over 4 yrs now! I have been doing all what I can as they stay only 2hrs from me. I told my dad not to say nothing cause I dont want to start any drama. I told my sister no to my 19 yro niece last year as she is a party girl and I felt that it would be a fight with me and her. My Sis was mad for 6mo! I need family more than ever and dont want no one mad at me. Anyway, my and my youngest (JJ) is going shopping and to a hello kitty bday party...help me!

didgeridoo - 1 days ago
Maybe it would be hard for him too to try and study in such a crowded house where there is a new born baby that will maybe (but hopefully not) cry at night and maybe he wouldn't even like it in the end!

didgeridoo - 1 days ago
Evans you are having a baby, it's okay to refuse. IMO, thinking of your mother and your children is NOT selfish. You seem very loving and accommodating and I am sure your family will TOTALLY understand! I have a lot of sisters, and sometimes it's really hard to say no when sometimes it is the right thing to do :)

evansbabyg - 1 days ago
ok, I just got a text from one of my twin nephews and he wants to stay with me while going to college. My heart wants to say yes, but the room that he would stay in is my guestroom for my mommy and my office when she comes. The other guestroom was turned into a gameroom for my fellas and DH. My office will be the baby room since it is close to our room....where will he sleep???? I dont want to shift my kids around and my mommy needs a bed to sleep in when she comes with her own bathroom. I dont know what to do? I dont want to seem selfish. I always seem to be the aunt that keeps all my sisters kids and Iam the baby of the family. Sorry to vent but I am so torn on what to do that will not cause confusing in my household...oh and then my hubby is having a house full of guys over to talk about his friends bachelors party so he is cooking and I want to vomit!

Momof2 if u decide on a IUD get the Mirena and not the copper one. The copper one just makes the uterus uninhabitable but there is still a risk of ectopic pregnancy. Basically the egg will get fertilized but it has nowhere to attach to. My periods were 7-8 days long and so sooo heavy I was severely anemic and eventually had to get it removed. The Mirena has hormones in it so it's basically like the pill you just don't have to take it every day, it lasts five years and you don't even get a period. Lots of people seem to love that one. I could also feel the copper one every time Me and my boyfriend got intimate, which was super uncomfortable! Not sure I that's the case with te Mirena as I think they are made of different material and I have never had one so I dont know.

evansbabyg - 1 days ago
oh I did not know that they push BC after you had so many children. I am not taking anything...anyway why dont they ask men this when they go to the doc? I told my DH and he said I agree as Iam not going to do anything to orevent either, so Iam glad we are on the same page. Wow how things change in 8 yrs! I think it is whatever you and your spouse agree with based on your family needs and religious preference. I thought it was just my doc???

Mom~of~2 - 2 days ago
With both my pregnancies my doctors were pushing birth control pills on me and I refused! I don't want to use birth control pills for personal reasons. However, with this pregnancy the doctor I have now said that I need to go on birth control because I am very fertile....I got pregnant and we were not trying...so that would be like a 5% chance I would get pregnant and I did! After this pregnancy I'm really considering putting in those iud's?? (spelling?) or going on birth control as I'm afraid I'll get pregnant again even if I AM NOT TRYING! I know that sounds weird but 3 kids under the age of 3 my hands are going to be tied up...I do want more kids but not now maybe like 4 or 5 years down the road and that's a big MAYBE. I am 30 so hopefully I'll have enough time to have 1 more if I am able to!

tanyaschmalz - 2 days ago
They asked a couple times last pg about what my bc plan was and I said none or condoms. I didnt even give her a chance to ask this time. I told her that I want my tubes tied. My hospital is religious so I have to go through an interview to make sure I really want it and understand what this means blah blah blah. I told my midwife I dont want to have a bunch of kids at rist of mental crazyness (I think my husband has more than bi polar, very paranoid). She totally understood. I love my midwife. Shes so personable. Oh and the site isnt fixed in full, my original name and Lisas name isnt on the side yet. I hope it gets fixed. (Destiny*Joshua...)

evansbabyg - 2 days ago
Does anyone feel like this is the last child they would have? I was reading a book about what my doc will discuss at my next appt and it is about birth control. i dont remember talking about that when I was pregnant the last time...is this something new?

Mom~of~2 - 2 days ago
Evans thanks for the kind words....your son will pick out the perfect gift for his 'friend' lolol How cute!!! looking forward for Luca to come up to me and say mom I want to buy a gift for a girl and I need your help! lol sigh...they grow up so fast don't you think? lol Mine is only 2 and he was really working all the girls yesterday! I couldn't stop laughing...they were in their 20's and he had them wrapped around his little finger LMAO...Have a wonderful day!

evansbabyg - 2 days ago
Gigi you are hilarious..lol...I dont never do that stuff cause I dont understand any of it...it says 50% chance it is right so that is like me guessing...lol. It is cold and I refuse to get out the bed. Since my kids are older they are very independent and my hubby is fixin breakfast. When my baby comes, Iam going to need some HELP! I have a new profound respect for the mommies who are pregnant with lo(s) at home.....Iam praying for us all and know this will be a new chapter in my life!

evansbabyg - 2 days ago
Thx momof2. I have not been on fb in awhile so I forget what pics on on there...lol..Your family is beautiful and I just seen your pic and you look like my SIL...I showed my DH and he agreed as well. You are such a pretty girl and do not forget that or let anyone tell you different...my youngest is a mess...lol. He has a bday party to go to and it is a girl. He told me that he wants to go with me to pick something nice cause she deserves it..lmbo? Really?

Mom~of~2 - 2 days ago
Evansbaby I must add...your son's are all very handsome! However, after saying that your youngest OMGGG can you say adorable???!?!?!?!?! lol omgoodness how cute is he! lmao Love his smile!!!

Mom~of~2 - 2 days ago
Glad the site is up and running again....Did not sleep for a min last night...I'm exhausted and very nauseous. To top it all off my company just confirmed they are coming tomorrow! Evans you should register at toysrus or babiesrus for your shower...you will get gifts you choose. My jeans were fitting me fine yesterday I just had to keep pulling them up. I need to start wearing my maternity pants as they are more comfortable and I won't have to worry about my crack showing while I chase my son around or pick up my baby girl! lol Have a good day ladies hope everyone is feeling better and the ms is all done for all of you!

ok, the old wive's tales questions I cannot fully answer yet. I am not really carrying high or low and I am not feeling any kicks yet. It said GIRL but like I said I gave a lot of false info due to not having any of the kicking yet. According to cravings and thick hair and so fourth, I am having a boy but at the end of the questions it said girl. I cannot understand how to do the chinese gender chart. it is weird. so help me out. my birthday is 08/27/1984, I conceived in Nov 2011, some time around nov 20th, I live in VA, USA, so eastern central time. I will try the baking soda test. Let's see.

gigijey - 2 days ago
Gosh, I have no time to come here anymore. I really miss reading about you all. I am reading about all these methods to find out what you are having and I was wondering if I should test some of them for you ladies. I know I am having a boy (chromosome analysis done at 11 weeks and they saw a Y chromosome) so I would like to know if any of the old wivestales or any other tests would come back BOY as well. curious. So tell me about the tests you would like me to do (except intelligender, I am not paying 40 bucks for a test :-)).
