15 weeks of pregnancy

15 weeks pregnant! Your baby has reached about 9,3-10,4 inches long from crown to rump (about the size of an apple). He trains in breathing, sucking amniotic fluid (amniotic fluid) in the lungs and pushing it back from the lungs. Amniotic fluid "updated" 8 - 10 times a day! This helps maintain their sterility, while maintaining the desired chemical composition (ratio of water, minerals and organic matter).
