Pregnancy Week 4

Pregnancy Week 4



Your Baby's Development This Week



Roughly the size of a poppy seed, your baby is now entering the phase of development known as the embryonic period. The cluster of cells that is becoming baby has traveled down the fallopian tubes and have settled into the uterus, where the next big task is to divide in half. One half of the cells become the placenta while the other half becomes baby. The baby cells divide further, into three groups. The first, the inner layer, is called the endoderm. The endoderm develops into the digestive system, liver, lungs, pancreas and thyroid. The middle layer, or mesoderm, becomes heart, reproductive organs, bones, kidneys and muscles. The outer layer, or ectoderm, becomes brain, spine, nerves, skin, hair, eyes, teeth, sweat and mammary glands. The amniotic sac and yolk sac are forming now as well. The yolk sac eventually will become part of the digestive system.

Pregnancy Symptoms You May Feel During Week 4



Bloating, cramping, mood swings, fatigue, headaches, backaches. Sounds a lot like PMS, doesn’t it? Early pregnancy symptoms are quite similar to premenstrual syndrome. You might feel more breast tenderness than you usually would with your period however, and your breasts might be enlarged somewhat. You may feel some abdominal pressure and might experience implantation bleeding. This is spotting, and may be light pink, red or brown. It happens when the embryo implants itself into the uterine wall. It’s not rare, but certainly not unexpected either. Whether you have spotting or not, you need not worry.

Visit With the Obstetrician



article continued below...




Usually you won’t be seeing a physician for your pregnancy until your 8th week or so. However, you will be taking a home pregnancy test at this point most likely. If it is negative, wait a week and retest. Sometimes the pregnancy hormones are still too faint at 4 weeks for many tests to pick them up. You can begin looking for a doctor or health care provider, and might interview the most promising prospects to see if you have a good match in expectations.

Preparing for Baby

This is a great time to just start reading up on early pregnancy. What foods are no-no’s? Which foods should you be eating? What are the exercise recommendations for early pregnancy? Is pregnancy going to be an issue with your work? Will you need to make some changes at the worksite or to your schedule? What is the maternity leave policy at your job? Thinking ahead, not worrying, is a good way to start preparing mentally for this new pregnancy.

Pregnancy Lifestyle



Check that medicine cabinet. Are there prescriptions drugs you take regularly? If so, read up on them or talk to your pharmacist about the safety of taking them while pregnant. If you find out a drug you take can be dangerous in pregnancy, talk to the prescribing physician immediately. Don’t wait until your prenatal visits begin. Also, check on any over the counter medications to see if they are safe to take while pregnant.

I am 4wk's 2 day's prego. My test came back positive at 3 wk's 4 days...my husband keeps teasing that it might be twins. not funny... :) I am exhausted with sore breasts, and gassy. If I could nap every 3 hours for a half hour my life would be perfect but that's not going to happen.

Not having any morning sickness. Going pee ALL the time, and I could sleep all day. Some crazy feeling cramps, that do not feel like menstrual cramps. Bloated. Test came out negative, but I would only be 4 weeks 3 days, so its most likely too early! Wish me luck!!

Just found out two days ago that I am expecting my second child. I have a son who is 18 months. I too was experiencing back ache and cramps that were similiar to my menstrual cramps. I bought a test for the hell of it and was delighted with the news. It will be a bit of an adjustment having a son that is two and a newborn, but I am so excited for the challenge!

Hi, I'm kind of hoping that I am pregnant. But I don't really understand the Symptoms, I do have the cramps, the backaches are slowly starting, but I'm not sure if I am on my period or the implantation thing.

I had a miscarriage on the first of December. Through the month two tests came out negative. On New Year's eve my test came out positive. I hope this is a real pregnancy and not remnants of my loss earlier in the month.

Just like to share my news of a positive test after 2 months of trying and at 42 feel very relieved. This is my fourth pregnancy and it's been very different to last 3 . That's what I want to share! Foul bitter taste in mouth on Tongue started a week ago. Bought Tongue scraper and mouth wash but it would not go away. Researched it and found alot of women experience it as a first sign of pregnancy! They were right ! Sore boobs tiredness and bitter taste! Now it's a positive not a negative and worth it LOL So an early symptom to be aware of : )
