Born & Birth stories

The crown-to-rump length of your growing baby is almost 2.5 inches and she now weighs between 8 and 14 grams! In just three weeks, fetal size has more than doubled and begins to look a lot more human. Even though you will not be able to feel your baby moving at this time, you can stimulate him and he will squint, open his mouth and move his fingers or toes.

By the end of this week, your uterus is too large to remain completely in your pelvis. You might be able to feel your uterus above your pubic bone. The uterus will continue to grow throughout your pregnancy and will return to its usual size within a few weeks after delivery. Before pregnancy, the uterus is almost solid and holds less than 0.3 ounces. During pregnancy, your uterus will become a thin-walled, muscular container that will hold the fetus, amniotic fluid and placenta. Before pregnancy, the uterus weighs approximately 2.5 ounces and when your baby is born, it will weigh almost 40 ounces!

Because most of the structures are already formed at this point, few will be formed after this time. The structures will continue to grow and develop throughout the remainder of your pregnancy. The skeletal system now has centers of bone formation in most of the bones. The digestive system is capable of making contractions that push food through the bowels and is also able to absorb sugar. The pituitary gland is beginning to make hormones. You will probably be able to hear the fetal heartbeat with a doppler at this time!

This week may be the first week that you begin to feel better! Morning sickness often tends to improve or diminish at this time. You may begin to show slightly, especially if this is not your first pregnancy. You will feel more comfortable in loose clothing, such as maternity clothes. In addition to your tummy getting larger , you may notice an increase of size in your breasts, hips, legs and sides.

Your baby develops reflexes and the skin is very sensitive.
The brain is fully formed and the child can feel pain. The baby may even suck his thumb. The eyelids now cover the eyes and will remain shut until the seventh month to protect the delicate optical nerve fibers.

Floyian - I'm not really feeling pregnant as all my symptoms have tapered off and I just feel 'normal' but the one thing is I am visibly pregnant now. I'm wearing black and long scarfs to hide it as we just aren't wanting to tell people yet. I can still fit my pants fine as long as they are low waist, but I've broken into the mat shirts because everything was just getting too tight.

Has anyone else experienced the feeling that, although you know you’re pregnant and even have symptoms, it all just doesn’t seem real? It’s been such a strange experience this time around. I’ve been doing everything right and staying healthy, I’ve been having all of the classic symptoms, and yet I haven’t actually felt pregnant. How weird is that?! Anyway, hope everyone is doing well!

Elequin...I can sometimes feel that's like feeling a pulse in your abdomen! That is your aorta, a major artery that connects from your heart all the way down to your lower abdomen and branches off to your legs! I pretty sure we're more likely to feel a pulse in our tummy because our heart has grown 12-15% larger to pump around the extra volume of blood our bodies make for pregnancy! Our bodies are amazing in pregnancy!

elequin - 6 days ago
My placenta is posterior, and that's the other thing I've noticed. I can actually sometimes feel my heartbeat in my abdomen. That sounds weird, but I wonder if its my placenta that I'm feeling?

Dec Baby - 7 days ago
elequin...i think it's awesome that you can feel the baby move! I'm jealous...hehe My baby is way down low with placenta at the front of my uterus, so I don't think I'm going to feel movement for a while! Each night I lay really still to see if I can feel the baby move but it hasn't happened yet:) I felt baby number 2, 3 and 4 really early, all of them around 12 weeks! My last pregnancies I haven't felt the baby till around 16 weeks, but I think it has a lot to do with where your placenta is positioned! I'm starting to feel much glad that the worst of morning sickness has passed...still throw up every now and then but it seems to be a lot better! I have had some interesting blood results showing that I have a high reading of antibodies which could be harmful to the baby:S So I'm seeing an endocrinologist on Wednesday to find out what it all means! Hope you girls are feeling better and your pregnancies are going well :) Keep posting girls, it's so nice to read, even the day to day things...elequin, I really felt for you when your hubby took out your frozen lasagne, grrr I wish you could come and cook for me, your menu sounded delish!

1st.time.momma - 9 days ago
Ive been getting some messages about mommies not finding the fb group still so here is the web address to find it. if yall still cant find it message me your email and ill add you. Now on that note I will be moving to 13 weeks tomorrow. So excited. Times flying on by

elequin - 9 days ago
Ok I know this site says u can't feel baby move yet. But I am definitely feeling it, even lined up with my ultrasound when I saw it kick and punch and bounce. Anyone else with me on this???

elequin - 11 days ago
Ooooh I LOVE the name Xavius :) might store that one up if we get a surprise with a boy lol :)

Hopin4ABoy31 - 11 days ago
JulesBaby My last normal cycle was in May and I spotted for a few days in June when my norm is usually similar to you about 5 to 7 days. At my ultrasound I apparently got pregnant 2 weeks after I spotted. And that was a first for the three pregnancies I've had. !st.time I know how you feel. I'm already rocking the perpetual sweat pants even though I've been losing weight! Pregnancy is crazy!

alismom2 - 11 days ago
Yay week 12. ..@ elequin yea we seem to have decided already as well! We picked Kaylee Rose for a girl and for a boy Carter Xavius (also his dads middle name)

elequin - 11 days ago
I am actually shocked. - I think my hubby and I are in agreeance already about names, providing we're having a girl?! We like Roxanna Leigh or Roxanna Grace. She'd be called Roxie though. I ran it past my 3 yr old and she said she liked Roxie for both a girl and a boy lol :) Anyone else chosen names?

elequin - 11 days ago
Jules baby I would say your spotting is prob implantation bleeding. Is it your first preg? I had this with my first two babies, at around 8 days late.

julesbaby4 - 11 days ago
Maybe someone in this week might know... Today's my 1st appointment & my last normal cycle was in June but after being 9 days late in July I spotted for 4 days (normal is heavy for 7 days) do I go by last normal cycle or the spotting in July?

Dec Baby - 11 days ago
A little update...we just had our u/s and saw a perfectly healthy little baby and at my age I'm so thankful! We did have a moment where we both held our breath, the sonographer couldn't find the baby when scanning over my tummy... The screen was just dark!! She ended up having to do a vaginal u/s! I was kinda surprised that the baby couldn't be seen via the tummy @ 12weeks 5 days?! So I guess I have a serious retroverted uterus! Baby measured spot on for dates too! Anyhow, super excited to share our happy news with friends:)))

1st.time.momma - 12 days ago
I know some moms couldnt find the fb iap page so I created one. I-A-P 2015 MOMMIES...if you cant find it message me your email and ill add you

babybubbles88 - 13 days ago
Good be 12 weeks! Tomorrow um heading to 13 weeks! I'm already showing a big belly. People think I'm over 20 weeks! I went to my 12 weeks check up I lost 2 lbs now only weight 96 lbs...hopefully will gain more by next week. See you all in the 13 weeks.

1st.time.momma - 13 days ago
This is my second and ive felt like ive been showing since 4weeks. My bellys been hard since then, all the way to the top of my belly. How do you feel your uterus? This go around feels like a whole new experience. The baby daddy is with me 100%. Goes to every appointment when with my 5 year olds dad was never there til after he was born/ even now. I often feel like a new mom and joke around saying i might not even know how to hold my

Hopin4ABoy31 - 14 days ago
1stmom27 I'd see your doctor about your discharge especially if it's green from time to time. It could be a yeast infection but usually the discharge is thick and white or yellowish. Green might be something else. I'd hate for you to go spend your money on the yeast infection stuff and it doesn't work. You could probably just call your doctor and they may see you earlier.

Hopin4ABoy31 - 14 days ago
Hello week 12!! I'm with you 1st.time I haven't been on in two weeks but I'm still like I have so much further to go! I feel huge already so I guess it's true that you get bigger faster the more kids you have! Luckily I'm not dying of exhaustion anymore lol! My other kids totally appreciate that! I still don't have an appetite even though I haven't really had any morning sickness which seems weird but I can actually feel the top of my uterus which means baby is getting there even though I don't eat much. Its all good to me! I hope everyone else is doing well!

Dec Baby - 14 days ago's common during pregnancy to get a lot of discharge! But if it's itchy down below, then I agree with the other girls...sounds like thrush! Easily fixed by going into a pharmacy and grabbing some thrush medication! Hope you get some relief soon!

babybubbles88 - 14 days ago
I searched for IAP 2015 and couldn't find it either

babybubbles88 - 14 days ago
Sounds like a yeast infection. You can get over the counter for those. It doesn't need to be prescribed by a doctor. Get monistat 3. I had one with my son and my doctor recommended monostat 3. It is cheaper with coupon or dollar store. - 15 days ago
Maybe a yeast infection. With my first pregnancy I got a couple of them.

1stmom27 - 15 days ago
Hi ladies, I have tried to search the facebook groups but couldnt find them :( so I guess ill ask my question here ... its kind of TMI .... I have a lot of discharge, its usually white or green and im extreamlly ichy down there... anyone know what it can be? I don't see a doctor for another 2 weeks.

1st.time.momma - 15 days ago
Yay 12 weeks today! Times going by so fast yet so slow. Hows all the mommas doing?

klawest2 - 17 days ago

cutey24u - 59 days ago
Back pain is back in the sacral region and nothing helps. I can't lay on my back because it is to uncomfortable. Not having any other pain besides minor stretching pains, no bleeding or anything. This back pain is ridiculous!
