Prenatal Development: Week 6
It's now four weeks after conception and, believe it or not, your baby is really starting to grow at a rapid rate! First, the umbilical cord starts to form and the neural tube along your baby's back has closed over. Also, the brain is starting to grow to fill in the now-formed, enlarging head.
This week, eyes also start to develop on the side of the head as well as the passageways that will become the inner ear. Buds that will later become arms and legs are also beginning to show.
Baby's First Heartbeat
However, this is a small step when we consider your baby's first heartbeat. Sometime this week, your baby's heart should start to beat even though it still can't be heard. Blood will then start to circulate. These developments are taking place on an extremely small scale, though - your baby only measures 0.08 to 0.16 inches (2 to 4 millimeters) from crown to rump!
Signs of pregnancy often tend to hit with full force this week. You could feel extreme fatigue, even before you know you're pregnant. This is because your body is adjusting to the demands of pregnancy. In addition, tender, aching breasts, nausea and vomiting, or morning sickness may leave you feeling less than great. It is also extremely important to start taking a prenatal vitamin right away. Make sure to choose one that's made without artificial dyes yet has the recommended amount of folic acid.
Risk of Miscarriage
Having a miscarriage is a very real threat at this stage of your pregnancy, so be sure to not over exert yourself. Also, keep caffeine intake to one cup a day and avoid any alcohol. Some of the signs of a miscarriage are:
- Passing of grayish or pinkish tissue
First Signs of Pregnancy: Morning Sickness
Morning sickness will more than likely be in full swing during this week, so keep drinking fluids to stay hydrated. Eating small meals and cold foods also helps. There are many home remedies including some specially formatted cds that help women through this uncomfortable time.
You may want to discuss with your partner when you are going to break the news of your pregnancy to everyone. If you are very queasy, people may be already guessing!
