Week Twenty: The halfway point
You are halfway through your pregnancy, 20 weeks marks the midpoint. Remember, pregnancy is counted as 40 weeks from the beginning of your last period if you go full term.
You are 20 weeks pregnant. (fetal age 18 weeks)
Your baby now weighes about 11 ounces and at roughly 7 inches long they are filling up more and more of the womb. Though still small and fragile, the baby is growing rapidly and could possibly survive if born at this stage.
Note: Babies are measured from the crown (or top) of the head to the rump (or bottom) until about 20 weeks. After that, they are measured from head to heel. This is because a baby's legs are curled up against the torso during the first half of pregnancy and very hard to measure.
Weight: 10.6 ounces - 300 grams
(crown to rump) 6.5 inches - 16.5 cm
(crown to heel) 10 inches - 25.5 cm.
