Week 20 Second Trimester


At this stage, you may notice a darkening of the line of skin between your belly button and pubic area (called the linea nigra). No worries though, it will fade after you give birth.

With your baby’s body growing bigger and bigger, there’s more pressure on your lungs, causing shortness of breath; your bladder and kidney, causing frequent urination; and your stomach, causing indigestion or heartburn. You might also be sweating a lot more, as your thyroid is more active.

If you haven’t already had one, your health care provider may recommend that you receive an ultrasound test (usually done between 18 and 22 weeks), which can determine the size and position of your baby as well as any structural abnormalities of bones and organs that are visible. The umbilical cord, placenta, and amniotic fluid may also be seen through the ultrasound.

Your Baby

Congratulations, mom! You’re already halfway through this exciting, roller-coaster ride of a pregnancy! At this point, your baby has grown significantly from that first dividing cell and now weighs about 312 grams and is about 16 cm in length. He is taking up more and more space in your uterus.

An ultrasound at this point may indicate whether your baby is a boy or a girl.
