Week 20. Half of your pregnancy!
You have already reached half of your pregnancy! We normally talk about 40 weeks of pregnancy heading from the last menstruation. However, the length can vary from 37 to 42 weeks. The baby is approximately 20 cm long and weighs about 255 grams. However, as you may know, the baby must still grow much more.
During the second half of the pregnancy the weight increases more than tenfold, (about 3 kilos) and its length will duplicate this week (it will go from about 25 to about 50 centimetres).
