18 Weeks (and a few days)
Well we were away over the (long) weekend, but here it is a few days late.
Your baby is approximately 6 inches/ 14.2 centimetres long from crown to rump and she weighs about 7 ounces/ 190 grams. Her chest moves up and down to mimic breathing but she’s not taking in air, only amniotic fluid.A mid-pregnancy ultrasound scan is often done sometime in the second trimester (usually between 18 and 22 weeks) to assess fetal growth and development, screen for certain birth defects, check the placenta and umbilical cord and determine whether the gestational age is accurate. During this scan, you might see your baby kick, flex, reach, roll, or even suck her thumb. If you’re having a girl, the vagina, uterus, and fallopian tubes are in place. If it’s a boy, the genitals are distinct and recognisable.
