Born & Birth stories





By the end of this week, you will most likely be expecting your period to come. However, if you are pregnant your period will most likely not come. Some women do experience some spotting or even a light period. It is also possible to have your period and still be pregnant! If you do miss your period, you might begin to think about a possible pregnancy! Home pregnancy tests are not as reliable as blood tests at this point. A blood test will detect a positive pregnancy test at this point because the hormone, human Chorionic Gonadotropin (hCG), has been secreted.

At this point in your pregnancy, your growing baby is very small and is about 1 mm in length. One mm is about half of the size of a typed letter `o`. You are still not showing at all and you have not yet gained any weight. Even though you are in the very early stages of your pregnancy, many great changes are occurring. The implanted embryo is embedded deeper in the lining of your uterus and the amniotic cavity is beginning to form. The placenta is also forming and will be delivering oxygen and nutrients to your developing baby. This week the blastocyst begins to transform into an embryo. The embryo will have three different layers with different types of tissue. The inner layer will form the lungs, liver, digestive system and pancreas. The middle layer will become the skeleton, muscles, kidneys, blood vessels and heart. The outer layer will become the skin, hair, lenses of eyes, tooth enamel and the nervous system.


A clear result. If you tried it a few days ago and the result wasn't as convincing as in this picture, try it again now to be sure!

Even though you have not yet gained any weight, you need to be prepared to gain weight during pregnancy. Gaining a healthy amount of weight is crucial for the health of both mother and baby during pregnancy. You can control your weight gain by eating healthy and nutritious meals and snacks. During pregnancy you are eating for two, but that does not mean you have to eat twice as much!

Your body now starts producing a hormone which stops you having your period, and it shows in your urine.

It is now possible for your pregnancy to show up on blood tests, and even home pregnancy tests.

About 1 in 3 women have a light bleeding at this point. This happens before you would expect your period to arrive. Unless accompanied by cramping, backache or increased bleeding, a small amount of blood being discharged should be considered as implantation bleeding which is nothing to be concerned about.

At this point, your baby is still not visible to the naked eye.

Got a faint positive last week on two tests :) I'm going to join the group, as far as I can tell, it will show up in your recent activities, but if (on a computer) click the little lock in the right corner, go to 'who can see my stuff' and then 'use activity log' it will open a screen with everything. Once your request is accepted, you click on all and it should be the top, and you just click the little pencil icon and click 'hidden from timeline'. and it should show then. :) This is my third baby, super excited :)

MrsBugs - 6 days ago
Hi ladies!! I think I may have just got a faint positive but the control line was weak too so idk??? If I join the closed group Facebook page that has been set up, can anyone reassure me that it won't show up in my newsfeed on my FB page as I absolutely don't want anyone to know at the moment that I have joined a FB pregnancy group!! Thanks in advance!!!

crummie - 7 days ago
Morning ladies. After just a short time of TTC, I got my BFP this morning. DD is 4/23! I sent a join request to the FB group listed below. My real name is Laura Branham. Hoping to make some great friendships here as I did during my first pregnancy. Happy to be back! :D

supermom87 - 9 days ago
Can being nauseous and vomiting a good sign that its possible I am still pregnant I haven't received blood results yet I'm having weird dreams back to back still cramping but not spotting anymore ugh just wish I knew if things could possibly be ok or not

Desiree.V - 11 days ago

supermom87 - 11 days ago
It a sucky situation I've had 2 miscarriages before this pregnancy so I'm very scared of it happening again my DH is trying to be supportive trying keep me calm I love him for that but I think I have made up my mind if I lose this pregnancy I am done cause I'm tired of the emotional rollercoaster

supermom87 - 11 days ago
Not really sure I just know with my insurance I can afford the doctors office visit and I can't afford hospital with it so I tend to stick to Dr office unless I have no choice but got to hospital

sher-baby - 11 days ago
Ugh! I'm sorry Supermom! Last year when I was cramping and spotting I had gone to emerg. They gave me my levels within a few hrs. and told me I was m/c'ing. Would it be very costly for u to go to emerg? Or do u think they would tell u the same as ur dr??

supermom87 - 11 days ago
Yeah the doctor drew blood to check my hcg levels to make sure I'm not miscarrying other than that she said wasn't much they could do she told me try not to stress relax when I can stay hydrated and they will call with my levels and let me know what's going on

sher-baby - 11 days ago
Supermom- I'm soo sorry. Are u spotting??

supermom87 - 11 days ago
I'm at Dr office now cramping so bad I don't think there is much that they can do if I am having another m/c :( all I can do now is pray my baby is going to be ok I'm thinking I got to hot working today plz be ok lil sweet pea

sher-baby - 12 days ago
beckybai1984 - i'm kmfx for you that hopefully its just old blood, maybe from implantation. I'm not 5 weeks until tomorrow but my CB conception indicator picked up that i was 5+ weeks (3+ weeks pregnant) on Saturday. I'm still not feeling pregnant though. no symptoms, just bloated like crazy!

beckybai1984 - 12 days ago
thanks supermom but im hoping im not speaking too soon ... Cus now like 2 hrs after my BFP I am now spotting - :(

supermom87 - 12 days ago
Congrats beckbai1984

beckybai1984 - 12 days ago
I just got 2 lines this morning!

supermom87 - 13 days ago
They did an ultrasound and it only showed the gestational sac I got to go back the 21 of this month for another ultrasound I already know I am having a C-section cause I have a a previous C-section also I am high risk

holz8519 - 13 days ago
Supermom87 that has happened to me with all 3 of my pregnancies did you go for an actual dating sono yet? A dating ultrasound around 6 weeks would be the most reliable dating method as the later you are in your pregnancy the more a babies measurements can vary. You probably have a due date based on a physical exam, one based on your lmp, possible ovulation, time of intercourse. Most OB's will send you for a dating sono if they are not sure. Though your dates are all within a week so Idk. The only time EDD matters is if your OB has to schedule a c-section in which case they tend to go by the dating of your first ultrasound. either 6 or 12 week scan.

supermom87 - 14 days ago
I've gotten so many due dates I don't know how to react I've been told April 9 April 10 April 14 and April 16 never had this many due dates my 7th pregnancy and my first time having alot of due dates when will I know my actual due date anyone else ever been through this

Sher-baby - 15 days ago
according to my LP I'm 4w3d but I tested again last night before I went to bed and my hcg line was like 3x darker than the control line. the control line didn't even show up until 3 mins after I pee'd on it! I hope this means my lil bean is good and stuck in there and producing lots and lots of HCG with hopefully just one lil bean!! I don't know how long I will be able to keep this a secret though. I have a pretty small frame as is but I still have such a bloat!! I know its not a 'baby bump' but it looks like one for sure....especially after I eat! I'm going to have to be creative over these next few months!

sher-baby - 16 days ago
My mom is my neighbor and I too am worried that she will notice or start to suspect. My dad just moved in with us but he's a lil obvious!! Jas-maybe u can get cranberry juice in a wine glass... It kinda looks like red wine.

holz8519 - 16 days ago
Jas77 same here Family get together this weekend and next weekend a family members wedding.

Jas77 - 16 days ago
Sorry for your losses girls. It's good to know that the chances of m/c go down with every week that passes. I'm always a little on edge during the first trimester.

Jas77 - 16 days ago
I have a couple of events coming up soon and I'm thinking people might be suspicious that I am pregnant when I refuse a glass of wine! Don't know how I'm going to get around this one lol. I have dinner with friends tomorrow night, sister in laws birthday Saturday and a big 40th next month. People are gonna know for sure......

shellybelly81 - 17 days ago
i think i accidentally deleted my comment. sherbaby- That's how my first pregnancy went down, had sex.. it wasn't like gentle it was normal, and i experienced some cramping, next day awful cramps, few days later... lots of blood. i definitely felt it was related as it happened right afterwards. i was reading an article it said once you reach 6-8 weeks your miscarriage rate drops to 5% and if you've already experienced one, a second one was only 3% chance. made me feel much better after reading it. i went on to having 3 healthy kids and now my 4th pregnancy

holz8519 - 17 days ago
I have also heard that opk can be positive if pregnant but I think later in your cycle not 5dpo. that's what has me so confused. However I went to the OB today so they could confirm my BFP and schedule my first appointment. Tuesday Aug 17th is my first appointment so hopefully they will schedule a dating ultrasound then and ill hopefully have a better EDD by the end of August.

Sher-baby - 18 days ago
im soo scared to have sex. I don't know if the 2 are related or not (it could of been just my luck) but with my last pregnancy, we had sex on the Friday, I started spotting on the Saturday and was m/c'ing by Tuesday. I already told DH 'we have to wait a couple weeks, I'm sorry!!' I booked my first prenatal apt for sept 8th and did all my blood work today!

shellybelly81 - 18 days ago
Yeah i wasn't too concerned as it was a tiny streak. ive been feeling dizzy on and off and just so tired. i made my first Ob appt, August 20!

Jas77 - 18 days ago
shellybelly- it could have been from sex, dark brown usually means old blood doesn't it? I'm not feeling any symptoms yet, have noticed my boobs are a tad bigger but that's it really. Oh I'm really hungry too.

shellybelly81 - 18 days ago
oh boy. so exhausted and crampy! i wiped today and it was clear cm with a dark brown line thin like hair. i don't have massive cramps or anything just normal ones but i wonder if its from sex? idk i actually spotted with my daughter at 5 weeks and that went fine. i still fit in my clothes but i notice my boob's Are growing

sher-baby - 18 days ago
soo why am i already having to look through my closet to find the loosest fitting jeans and tops!!!..please tell me im not alone! this bloat is sooo uncomfortable and sooo bug!!! *sigh* am i going crazy??

bean79 - 19 days ago
holz8519 - I've never used OPKs but I have heard they can be positive if you're pregnant. I also ovulated on the 15th and I calculated my due date for April 7. I think it's possible you really did conceive on the 15th.

sher-baby - 19 days ago
So clearly I suck at keeping secrets...I told DH on Saturday! Lol!!! But we'll prob wait to tell my family just incase...I want to be out of the danger zone first! We'll see!

bean79 - 19 days ago
I told my family the day I was positive that I was actually pregnant (which was 12 dpo!) so super early. I can't hold it in. It's our 4th. I haven't told friends yet because they would think I was crazy for telling them this early, but both our families now know. I wish I could wait till 12 weeks, but I am just way too impatient!

holz8519 - 19 days ago
We are trying to wait till 20 weeks before telling anyone. This is our 7th pregnancy and if all goes well our 4th child. We have a 9,3 and 1 yr old. This will probably be our last so were keeping it to ourselves for as long as possible. So we have a while to come up with something clever. we should be about 20 weeks around thanksgiving. I love your idea sherbaby this baby is due 4/12 though c-section would be a week or 2 before that and my sons are both born in March and my daughter in May so all my kids are gonna have their birthday right near eachother. lol.

Jas77 - 19 days ago
That's a nice idea sher, have you told your daughter yet?

sher-baby - 19 days ago
Jas77- haha!! Ya I think my mom will be shocked too!! I had a good idea to tell my family. I think Im going tell them all (and my daughter)at my daughters 6th birthday party by getting her a t-shirt that says 'I'm gonna be a big sister'...lmao! I think that will send everyone for a loop

Jas77 - 19 days ago
sher-baby I haven't told anyone yet, we are going to wait until at least 12weeks. This is our 5th baby (we will have 5 kids aged 7 and under when this baby comes) and I think my Mum is going to be a little shocked! I'm nervous about telling her haha.

holz8519 - 20 days ago
Hi all got my BFP at 8dpo due April 12th. Slightly confused as to when I actually conceived cause i was quite sure i ovulated on the 15th but then a few days later when all my ovulation symptoms returned though not as strong I decided to take an opk and it was positive stating i ovulated on the 20. Now I am still nursing my almost 17 month old and got my bfp fallowing my first postpartum period. So many say it's not possible to ovulate twice though i kinda think i did 5 days apart. which would make more sense at to why I would have been able to get a BFP at 8DPO if I did in fact ovulate twice I could have also been 13 DPO so IDK guess we'll have to wait till my dating sono. Just excite that and hopeful all goes well the next 36weeks :)

sher-baby - 21 days ago
Hi..I got my bfp today at about 12dpo, cd25. Af wasn't due until Tuesday but I got my bfp earl. I'm also very campy, not very painful just discomfort. I also feel like I need to go #2 all the time (sorry tmi) anyone else noticing that??.also, have any of you told anyone yet?? I haven't even told DH, I think I want to wait until after my dr's appointment to see what my numbers are at. I would like to not tell him at all until his birthday (Aug 26thth) but I don't know if I can keep it a secret that long AND he'll probably ask me!! I told my BFF only because I HAD to tell someone or else I'd go crazy!! I'm Looking forward to a h&h 9 months and I wish you all the same!!

bean79 - 22 days ago
I got a BFP this last Sunday. I was 11 dpo so I found out pretty early (period wasn't due for another 2 days). I'm feeling OK but lots of symptoms. Since this is my 4th, I knew very early that I was probably pregnant by the signs! So excited to be back on here, even though this baby is a total surprise!

shellybelly81 - 22 days ago
got my bfp yesterday :)

Jas77 - 22 days ago
Hey ladies got a BFP 2 days ago. I will be having my 5th child! Super excited. :-)

pumpkinfairy - 26 days ago
hi ladies, I havent tested yet but will soon. so far lots of cramping like my periods coming but she doesnt show, slight naseau, dizzy, very tired, and nipples feel like theyre on fire, do any of you that had a positive test feel the same way??

redbeamer - 27 days ago
So here I am again... Pg.. I just found out!! Wasn't planned... But will definitely be welcomed with open arms !!!

RJean - 27 days ago
Just found out we are expecting again! I had a miscarriage back in November, so I'm really hoping that this LO sticks around! Congrats to all of the other ladies, I'm excited to spend the next eight months with you!

justonemore - 28 days ago
Just found out that im expecting.... due date is March 30,2015

klawest2 - 31 days ago
Just got a positive pregnancy test on Sunday :) haven't had a period since May... I know I concieved this month though. I think I'm around 4 weeks but won't know for sure until the first ultra sound! This will be my second. I've already been experiencing some 'cramping' and nausea

floydianslip2 - 33 days ago
Anyone else have cramping that they are concerned about? Such an odd feeling, it's not like a menstral cramp, feels more like pressure/pulling. I read that it could just be the uterus growing, but isn't it a little too early for that?

mommylh - 33 days ago
Hi Ladies, I'm officially in! Tested yesterday and got the positive. Super excited, this will be number 3 :)

lisa.perez1983@yahoo.com - 34 days ago
This is my second time on here...had my last in 2009. I think I am 4-5 weeks pregnant. I am actually a surrogate this time around and had my transfer June 30th. I know my due date but not 100% sure on how many weeks. Happy to be back here though. Going to be a bit different this time around :)
