Pregnancy By Weeks – Week 20

At week 20 the baby is about 6 ½ inches long and about 10 ounces in size. Normal pregnancy lasts 40 weeks so at 20 weeks you have hit the half way mark, 20 weeks done, 20 weeks to go. This is the classic time when we expect people to feel some movement. This is called quickening. Most women actually feel movement before week 20 and some after. But the majority of women will be feeling some fetal movement at this time.

At week 20 taste buds are beginning to develop. This means that the baby will be able to taste differences in the amniotic fluid. The bigger point is that all of the systems are developed and functioning. The small details and fine tuning in development are happening now.

At week 20 the uterus has grown to the point where you can feel the top of it at the belly button. You can feel it yourself. Place your hand on your upper abdomen and press down, now move your hand slowly down your tummy. When you get to you belly button you should feel a hard mass, this is your uterus where the baby is growing and developing. Your doctor will begin measuring fundal height. This is the measurement from the pubic bone to the top of the uterus. From about 20 – 30 weeks, the fundal height in centimeters is about the same as the pregnancy in weeks. At 20 weeks the distance from the pubic bone to the top of the uterus is about 20 centimeters.

As the baby’s movement becomes more obvious you will start to recognize patterns. If this is not your first pregnancy, you may notice that these patterns are different from your other pregnancies. This is because each baby is unique and has its own personality. I always find it amusing that some people believe personality is an entirely learned behavior. Anyone that has more than one child will tell you that each baby is born with their own personality and these personalities express themselves in the womb before the baby is even born.
