Content: What happens in the 2nd and 3rd Trimesters? The second trimester is week 13 – 27 and the third trimester is from week 28 to birth. In the second trimester, during weeks 15 to 18, fetal movements begin. In weeks 19 – 21, the baby can hear and you may feel fluttering in your lower abdomen. At week 22, you will begin to feel the baby moving and a fetal heartbeat can be heard with a stethoscope. The baby develops a startle reflex at about week 26 and rapid brain development occurs as you move into the third trimester. In that final trimester, the nervous and respiratory systems develop, bones begin to form and fingernails and hair grow. How can I follow my baby’s growth in detail? In order to understand in detail how your baby is developing between prenatal doctor visits, refer to the Pregnancy Calendar.
