Your baby at 19th week of pregnancy

Your baby at 19th week

Your baby is the size of a large mango. Your little one is about 17.8 cm (7 inches) long and weighs anywhere from 185 to 226 g (6.5 to eight oz). There's a definite upswing on the fetal growth chart now, so expect some big gains in the coming weeks.

Extra eggs

If you're carrying a girl, her little reproductive system is already well established. The vagina, uterus and Fallopian tubes are all in place and the ovaries contain more than six million primitive egg cells. When she is born, that number will have shrunk to about one million. 

You've got male

If you're having a boy, his testicles have formed and have been secreting testosterone since about week 10 of your pregnancy. The external genitalia, which became male in the first trimester, are continuing to grow.

Second skin

Around this time, the skin starts to produce a waxy coating called vernix caseosa. Made of oils secreted by the skin, dead cells and lanugo (the fine hair that covers the body), vernix protects your little one's skin from the effects of floating in amniotic fluid. Most of it will disappear before birth, but premature babies are often born with a lot of vernix.

Funny face

Hormones are to blame for the “mask of pregnancy”–the brown splotches on your nose, cheeks and forehead–and the linea nigra, the dark line running down your belly to your pubic bone. Both gradually fade after you give birth, but exposure to the sun can darken the pigments in your skin even more, so be sure to use sunscreen.

Round ligament pain

As your uterus grows, the round ligaments supporting it have to stretch. Occasionally, these stretched-out ligaments will cause a sharp pain or a dull ache in your lower abdomen, usually on one side or the other during 19th week of pregnancy. It's probably most noticeable when you change positions or get up suddenly. Call your doctor if you’re worried about the pain.

Twin development at week 19

Your babies’ skin is now coated with a waxy substance called vernix caseosa. It protects them from wrinkling or scratching in the amniotic fluid.
