So Ive reached 20 weeks, the half-way point. Im so thankfull and thrilled Ive made it this far. Still feeling the bubbles, I know soon they will turn into kicks. Hopefully soon David will be able to feel them. I hope to take a belly pic next week when we get our ultrasound done (3/26/09). Stay posted for the pics!!! Ive attached a summary below on what should be going on this week.
Congratulations! This week marks the half way point of your pregnancy. It has been 18 weeks since the date of conception and your baby's crown-to-rump length is 5.6 to 6.4 inches (the length of a banana). The fetus weighs about 9 ounces and your belly definitely has an obvious bulge. Your waistline has expanded and is no longer visible. Your uterus has now moved up enough that it is pushing your abdomen outwards. The top of your uterus is even with or just below your navel.
For the remainder of your pregnancy, the growing uterus puts pressure on your lungs, stomach and kidneys. This will make you feel short of breath, the need to urinate more frequently and can cause indigestion. The added pressure on your abdomen can also cause your bellybutton to protrude and cause an `outy` instead of an `inny`. Many pregnant women begin to notice stretch marks around this time as well. Your abdominal muscles are being stretched and pushed apart as your baby grows inside of you.
Your baby's skin begins to thicken this week and will develop four layers. Your baby's sebaceous glands secrete a waxy substance called vernix caseosa. Your baby will be born with this wax and it will look like paste. The vernix caseosa is crucial because it protects the fetus' fragile skin from the continuous immersion in amniotic fluid. Lanugo hairs secure the vernix caseosa in place and it is thick around the eyebrows. Scalp hair and toenails are beginning to form at this point. Hair can also be seen on the upper lip and eyebrows.
