Month 4 ( 13-16 weeks gestation)
You have now entered the second trimester of pregnancy. Your baby grows from 3-4.5 inches (8-10 cm) long and gender may be discovered on ultrasound.
You may notice some pregnancy symptoms like nausea decrease while others like heartburn or constipation increase. Your body’s blood volume continues to rise so shortness of breath, feeling faint/dizzy, and bleeding gums may occur.
Month 5 (17-20 weeks gestation)
By the end of this month, your baby is approximately 6.5 inches (18 cm) long and begins to grow hair. A protective coating called vernix has formed over baby’s skin.
If you haven’t noticed the baby moving already, month 5 is where it is most likely to occur. Fetal movements are referred to as quickening during this time. Breast changes, shortness of breath, constipation, and heartburn continue
Month 6 (21-24 weeks)
Your baby is now 8 inches (20 cm) long and has grown eyelashes and has taste buds!
You may begin to feel your first contractions. Braxton Hicks contractions can present with painless abdominal tightening and your milk may start to come in.
