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.

Buntis-I was considering home birth, and would still consider it an option if my insurance covered it and I wasn't so nervous about something going wrong being a first time mom. I couldn't handle a midwife bill and a doctors on top of that.

alittle88 - 1.6 hours ago
yeah i am using Cetaphiltoo. i was using proactive because my acne started getting really bad around october when i stopped taking birth control. then i was diagnosed with rocesea so had to stop proactive. now i get these horrible zits i wanna rip my hair out!! I stopped taking the pill and became a teenager again!! now its just worse. i dont wanna go outside! thank you for letting me vent :)

buntis - 1.6 hours ago
Hello ladies! Hope everyone is well and happy. Just a quick question...is anyone else here considering homebirth?

sfrizzell1 - 2.1 hours ago
Mrs. Riddle, I have those pains too and I've read a few others on here that have posted comments about them. It's round ligament pain just another reminder that we are all about to blow up! LOL About the Acne, my face has been breaking out too and it always does during pregnancy. I did go to the dermatologist and got some medicine which I spent $65 on. Got home and read the warnings and now I'm not totally comfortable with using them. My derm did say washing with Cetaphil is the best thing we can do right now. She's prego also and thats what she's using.

mrs.riddle - 2.8 hours ago
Ok, so I've been having a weird, kinda painful spasm or something in my lower abdomen on the right side. It last like 2 seconds and then gone. I have them when I am sitting down mostly and sometimes when I am up walking around. It is such a strange feeling!! Should I be worried? Hope everyone has a wonderful 4th of July tomorrow! My grandfather passed away today from cancer. I am glad he is out of pain!!

Bri - 6.6 hours ago
alittle88 - Oh honey! I broke out my entire pregnancy last time and it looks like I'm doing the same this time. I never had bad acne but now I feel like a teenager! It's crazy, it's those damn hormones! Some women have a beautiful glow while pregnant and others get...welll...zits! Ugh! HAHA! Wash wash wash it'll kind of stay under control...kind of! HAHA! It goes away after birth

alittle88 - 6.7 hours ago
If i wasnt pregnant right now I would be starting AF this Sunday. Now why the heck am I still breaking out like a teenager right before my period? Seriously, i'm pissed!

HelluvaAngel - 10.3 hours ago
My Dr. just called 30 minutes ago and it's good news. My levels were 98 138. So I am no longer worried. My morning sickness is completely gone and my I am able to stay up late again. LOL! I have started getting the round ligament pain again though, but have read that this is normal again around the 13th week. Is anyone else starting to get these pains again.

Lizzard55 - 11.1 hours ago
Kabee- I am having the same problem. They haven't checked me for much yet. I get to hear the heart beat July 21st. Quick question for all you ladies... I didn't really have any morning sickness so far but it seems the past three days or so, it has gotten progressively worse. I can't sleep and I throw up, its horrible. I think I am going backwards in my pregnancy!!! Any others having this issue??

bellyfullofjelly - 11.3 hours ago
my day started so early today i hope i can make it though the day without any sickness today lol. i am hungry sitting here at work and just waiting to go for lunch...i still haven't told anyone about me being pregnant and i am not sure when or how long i can pull this off...i am waiting for my first ultrasound then i will tell people about me. anyways ttyl ladies....

summer83 - 13.4 hours ago
Hi ladies, it's my first day in week 13. Hope everyone is feeling better, I'm feeling great. X

MyBabySuprise - 14.2 hours ago
PreggerArmy wife, I am jealous as I would love to move closer to the 2009 birth line (lol) but the earliest this baby was concieved was April 12 so I don't think that is happening.

MyBabySuprise - 14.5 hours ago
I had a series of bad dream last night. One of which, Jack Black was delivering my baby (he wasn't funny either) and he had a diaper on made out of duct tape and three bands of duct tape around his chest and that was it and he kept trying to break my water while I was tied down. I think I need to relieve some stress.

PreggerArmyWife2010 - 1 days ago
Hello Ladies..Well I find out today that tomorrow I will be 14 weeks..So today is my first and last day in week 13..Wow that sure went by fast..Im looking forward to going through the rest of our pregnancies together and getting to know each other! I just can't believe that I was that far along..Due date is January 1st, 2010 congrats to all of you mommies!

angel1973 - 1 days ago
I should be able to find out the sex then. I don't want to know before that because I don't want to hear 'well it MIGHT BE...'. I want to know for sure. I remember with my son I had an ultrasound at 20 weeks. I had to drink so much water that I threw up. Then I stopped to pee twice before I got to the hospital. I am soooo happy that I don't have to have a full bladder for this one!

Bri - 1 days ago
angel1973 - That's awesome. I have the level 2 done as well but my doctor doesn't do it until 20weeks. It's long. Last time it was over two hours long. They look at every part which is cool but long. The reason for the full bladder in the beginning is because the bladder helps to push the uterus up, closer to the surface. I'm excited that some of you have found out what you are having already. That's cool. I was looking during my last u/s but I didn't see anything. I already have a feeling that it's a girl. We'll see? Boys are easier to spot then girls. HAHA! This next u/s I'm leaving Kekoa at home. He'll be too bored to sit still. HAHA!

jessica holt - 1 days ago
ANGEL1973- WILL YOU BE ABLE TO FIND OUT WHAT THE SEX IS THEN?

angel1973 - 1 days ago
I have something to make you all hate me.... I'm having the Level II Ultrasound done at 17 weeks. This ultrasound does not require a full bladder. My doctor told me today that this will take the place of the 18 week one that they would have done in her office. That means I don't have to drink gallons of water and be sooooo uncomfortable for over an hour. This just made my whole day!!! Well, that and the fact that I heard the heartbeat for the first time on doppler!

Bri - 1 days ago
I still get queasy every once in a while too, sometimes after food as well. I was like that until abou 18 weeks. It's nothing compared to what the sickness was like earlier this time so I'm actually excited it's only a little sick. Not down right, hugging the toilet sick.

Bri - 1 days ago
alittle88 - You can request an induction usually for a reason like you like a million miles away or something like that. But...take it from experience it doesn't always work. You have to be ready to give birth. I had a severe case of PUPPPS. It's a pregnancy rash that left me with lots of pain and now about 50 scars to show for it. I wasn't effaced at all so I was going in for a dose of gel to soften the cervix. I went in every other day for three days. You need to be about 75% to break the water. It got me to 60%. I then went in at midnight for pitocin. We were hoping the hormone would kick labor in and help me efface enough to break the water and really get it going. No such luck. By midday my doctor was going to send me home. I was on so many drugs to stop the pain that I couldn't take it. I broke down. When you haven't slept in monthts you kind of do that. I was so mad. I told her I didn't want to leave the hospital without a baby....so....I elected for a c-section. This is something that I didn't want. The comparison, I had chicken pox when I was 18months so I don't remember it. But, that's was my welts looked like. They itched so badly and hurt like Hell. I got it about 30weeks in so it's like having chicken pox without the fever for over two months. I was 39weeks when we did this. My body wasn't ready. She said it would be another two weeks before I went into labor. No thank you!! HAHA! I did want an all natural no drugs birth. That's what I want this time around. I know it will be harder being a VBAC but I know we (baby and I) can do it.

MyBabySuprise - 1 days ago
Kayutay, that is awesome. I know it is really early but she zoomed in and explained all the reasons she thinks it is a boy. Small chance she could be wrong so I am not buying blue yet. Jessica, my OB is a high risk one so I guess the do a lot more u/s and some extensive checking. At least when you get yours it will be much more likely that it is accurate

kayutay - 1 days ago
omg,..i also saw the baby drinking!! it was crazyyyyyyy the tech. was laughing hard

kayutay - 1 days ago
Mybabysurprise - I just had my nuchal too yestserday and tech. thinks i may be having a girl! she showed me the thing that you look for the #11 for a boy and equal sign for a girl (coz really at this age the Pns is the same size as the Cltoris),..plus she said the heartbeat is for a girl,..i was like whaaat..ok! never heard of that before but she said she's betting 70%..we were there for 40 mins trying all kinds of stuff to make the baby lay flat, its was fun to watch the baby move a lot!

bellyfullofjelly - 1 days ago
every time i eat i seem to feel queasy afterwards i was wondering if anyone else feels this way. sometimes i don't even want to eat at all, i actually tried it one day and by 4:00 in the afternoon i was really queasy no win situation for me. but i know this feeling will go away soon, this is the stranges thing to me because with the other kids i had no m/s at all or queasyness.

jessica holt - 1 days ago
mybabysuprise- I can not believe that you found out. I am so jealous. I need your doctor. This is not fair

MyBabySuprise - 1 days ago
It's a boy. The baby was being stubborn for the nuchal test today (despite the talk I had with him) but he was kicking up a storm with his legs spread wide and there it was. The u/s tech said it isn't 100% because occassionally a girl can have something proturding as well but this is most likely a boy. Yeah. Oh, and he did have a nose so I am excited because I couldn't make it out last week. This was my 4th u/s I will have the 5th on July 9 or 23rd b/c those are my next appts. Ask your dr if they can check for the sex when you go in just in case.

jessica holt - 1 days ago
mama-to-be09- I got a ultrasound then also and probably not until 20 weeks which is when I find the sex out. I dont see what the big deal is to just take a quick look.

mama-to-be09 - 1 days ago
I'm jealous too! I saw my baby at 7 weeks only because I went to the ER! I dnt get to see baby til 20weeeks! Were thinkIn of paying to see baby in about 2/3 weeks but I dnt kno yet. alsoo I think I've felt baby again a few times today ;; wasn't gas or hunger...

jessica holt - 1 days ago
alittle88- I am feeling the same way. I hope that I go into labor in Dec or hopefully my doctor will induce me. I would hate to pay two deductables. I am going to try everything I've heard of to go into labor early. I am also jealous that everyone is getting to see their babies. I have an apt on the 20th and I am going to try and ask for an ultrasound. I want to see what he/she looks like :(

kabee - 1 days ago
Lizzard - LOL. You are so funny, yet that is exactly how I felt towards the end of my last pregnancy. There were just alot of 'quickies' because it was uncomfortable and we were only limited to one position so it was not as fun. TMI. hehehe. I'm so jealous of everyone seeing their babies several times. My next appt isn't until July 17 and who knows if that will result in an ultrasound. hopefully i'll be able to hear the heartbeat though. I haven't heard it yet.

alittle88 - 1 days ago
okay so i have a question if anyone knows the answer. I dont see my ob again till the end of the month otherwise i'd just ask her! I see alot of mommies on here who have been getting induced at like 38 or 39 weeks. can you actually request to get induced early if the baby is good to go? i'm due in Jan 1st but ive got a $5000 insurance deductable (yuck) whick renews on that day! thats too much money!!! just wondering!

bellyfullofjelly - 1 days ago
yesterday i was on my feet all day with the kids celebrating canada day. by the end of the day i had a little pain on the sides of my stomach and i am not sure what it was, but as soon as i went to bed i felt fine. so what was it i don't know find out next doc appt.

sfrizzell1 - 1 days ago
Back from the doctor and was able to get my ultrasound on DVD plus pics of the baby. This child is STUBBORN! I could have found out today if I'm having a boy or girl however the baby had it's legs crossed the entire time and had the umbilical cord running through it's legs. Now I have to wait until 20 weeks before my next ultrasound to find out the sex. BUMMER!

racho - 2 days ago
sorry everyone, I have to leave u now for week 14. But I do send good thoughts ur way and hope everyone starts to feel better. After all, week 14 begins the 2nd trimester...which they say is the best! See u all in week 14!

Remembering headaches. The FDA in the US is trying to lower the aseinaminphin (sp?) over the counter dosage! This means our wonderful tylenol won't be as strong. I doubt it'll go through but seriously people! They are trying to lower it 35%. But, my thoughts are...if someone can buy a bottle that is 35% lower then instead of taking two pills they'll just take three. That's the problem I guess. Too many people are overdosing. People don't realize many meds like Nyquill has tylenol in it. So, they take both. They also want to pull any combo meds off the market. My husband loves loves loves Excendrin Migraine. I have to admit it works wonders although I can't take it right now. Ok, so my rant is about stupidity! The government can't stop stupid people from overdosing! If they are stupid enough to mix drugs then they will do it no matter the dosage.

alittle88 - 2 days ago
went to the ob yesterday for my headaches, she gave me today off so i could stay in bed all day and whats best is today was my birthday!! had a super-lazy perfect day lol! headaches finally gone but recently been having issues with my sciatic nerve. its so bad at night that it feels like someone is stabbing my ass haha. so my DH spends 15 min a night stretching me every which way. it really helps me thru the night. but now since it gets worse the bigger i get ob says it time for physical therapy yay ick. OH and we finally got to hear the babies heartbeat on the dobbler!! was starting to lose hope :)

Lizzard55 - Go to Gap.com....well at least I think they should still carry them. I bought them last time around and haven't been to their site yet this time. But, they aren't maternity but they sell them on the maternity page. They're their body by Gap or whatever they call it underware. They are very comfortable. Cotton and they sit right under the tummy. I loved them so much I kept wearing them....Not the sexiest things on Earth but comfortable. You can also buy thongs and such. Oh and I thin Old Navy online maternity also sells maternity underware.

Lizzard55 - 2 days ago
Mrs. Riddle- I am having the same problem!! Yesterday I was almost imobile because I felt so horrible!!! I felt like I had motion sickness. As long as I layed still I was OK. The minute someone would move the bed the slightest bit. I would get sick again. I don't know what that is from!!

Lizzard55 - 2 days ago
Angel... Get used to it!! When you get a huge belly you will finally just yell ' JUST SCREW ME ALREADY!!' ha ha ha. It IS nice knowing that he actually cares, but in that type of mood you are only looking for one thing! Good luck with that. My sex drive has always been up. My husband can't keep up with me! Applejax... I just bought two sizes bigger than I normally buy. It is working for now but if my belly gets super big I don't know what I am going to do!

angel1973 - 2 days ago
This is my boyfriend's first child. Our sex life never slowed down at all, but he has reached the stage where he's always asking if I'm ok with every position change. Annoying, but sweet. I imagine it will only get worse as my belly starts growing.

angel1973 - 2 days ago
Going for another doctor visit tomorrow. I asked for this one because I am going on vacation Sunday. This way I can relax and enjoy my vacation knowing that I reached 13 weeks and my little one is ok. Hope to hear the heartbeat, but if not...guess I get some more pictures!

applejax - 2 days ago
I never bought any maternity underwear last pregnancy ...just got large sized cheapos..did the trick! On the subject of sex..its all a mind thing for me..I can totally NOT want anything to do with it..but if I think of naughty things for awhile bingo bango I am hunting down my hubby hahhha. It`s great for him and me cuz I`m already in the mood and he doesn`t even bother asking me while I`m pregnant cuz he knows I flip flop so much he can never tell when I`ll be willing hahahhahh ohhh poor boys :)

Lizzard55 - 2 days ago
Hey ladies!!! Quick question... Do you know of any stores that carry Maternity underwear? I went to Target and to Walmart and they don't carry them anymore. I am not going to buy them from Macys or a department store just to wear them for another 7 months!!! any ideas?!?! Thanks!!

sfrizzell1 - 2 days ago
OMG! I have had this cramp in my ass for 2 days and it wont go away. I'm so glad I go to the doc tomorrow so I can figure out what it is. On the bright side, I get to see my little one tomorrow while I explain my ass cramp to the doc. LMAO!!!!!
