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.

cutey24u - 29 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!

Nicola, wow how neat would that be if you had twins! When so you go for a scan?? I go this week for another one! So question, how many of you ladies are drinking coffee?? I stopped for my first trimester but am just dying for a coffee! So I think I'll splurge once in a while! Thoughts? With my first I didn't drink coffee at all even when I wasn't pregnant, but that changed after I had a new born ;) and now I just mis it!

NICOLA2010 - 33 days ago
i cant wait for my ultrasound i still think i have twins.. i woke up this morning hard lump in middleof my uterus... i never hsd this till much later in my other pregnancy

konepich - 34 days ago
Had a rough day. Many back and stomach cramps. Spent the majority of the day in the bathroom. Hoping 2nd trimester is better.

NICOLA2010 - 34 days ago
im 11 weeks 3 days and suddenly have my appetitie back... cant stop eating.. anyone gained weight already? i know i have.. i never did with mu other two - 35 days ago
Babykhan, I'm doing ok, happy that that second trimester is just around the corner. I had the same situation with my son. They told me he was a boy around 14 weeks and he is very much a boy as well, lol; that's why I was kind of hoping they'd take a guess but oh well. I have a lot to do in the mean time; i suppose I don't have to start buying little outfits yet, lol.

babykhan - 35 days ago Thanks dear, i am doing well. How are you? I have heard stories that gender part looks almost the same around 12 weeks! But with my son i went for NT scan at 13 weeks, they told me a boy and he was very much a boy. Lets see if they're right this time around! - 35 days ago
Fingers crossed we all start feeling better soon!! I'm hoping for some second trimester energy soon lol I feel like a useless blob all the time I'm so tired by the end of the day! - 35 days ago
Chsaamanen, I'm in the same boat. I felt a little better a couple days last week so I thought I'd for sure be better this week :-( Ik it's just around the corner though and seeing my little one again reminds me what I'm going through this for, lol. - 35 days ago
Babykhan! Congratulations on your little girl! I had my second ultrasound today and she didn't look; she said it is too early to tell :-( ...happy for you though! How are you feeling? - 35 days ago
Hello week 12! Still exhausted and nauseous hoping that eases up soon!!!! How's everyone feeling?

babykhan - 36 days ago
Hello ladies how are you? me doing great. I had NT U/S yesterday, everything went well and Dr. was nice enough to look for gender and he told me i am having a girl! So excited! :) - 37 days ago
Yay!!! Week 12!!! Morning sickness will be gone soon!!!!!!!!!!!!!!!!!!!!!!!! :-)

Trini - 40 days ago

su90 - 46 days ago

I yell at everyone for eating anything of mine. Come on people! I'm on a limited amount of food I can eat. That means back off of my pop tarts, bagels, and ice cream!

kathy=^.^= - 69 days ago
Omg I yelled at my husband for eating my hot

kathy=^.^= - 69 days ago
Jh** no updates just taking it day by day go back to the dr on the 30th gonna ask for an u/s though to check on things. Just listened to my baby's heartbeat. So glad that I have my Doppler I would go crazy without it.

jh1983 - 70 days ago
kathy// how are things going with you? have you had any updates?

kathy=^.^= - 72 days ago
Lissie*** that sucks that you still feel that way. I don't feel pregnant at all. Sometimes it makes me worried. I use my fetal Doppler almost everyday just to check for the heart beat. The bleeding is killing me. I've been bleeding since April 20th. Still haven't told people that we are pregnant. My dr gave me a scare last week which made it uncomfortable to tell

desireed4 - 72 days ago
So glad to be almost done with the first trimester. Need my energy back

lissie**** - 72 days ago
Glad to hear you are well Kathy. 12 weeks is a big milestone. I'm 14 now and still sick but I have more moments of not feeling m/s. I'll take that! Still really really tired. HOpe that ends soon. I need the energy for me 4 kids and house. I seriously had to do a huge huge clean this week b/c I had let it go to hell. I've just been so sick/tired but I couldn't take the clutter and dirty bathrooms any more so I went crazy on the house. It feels so nice now that its clean again :))) now I need energy to keep it this way.
