What happens in the 13th week of pregnancy? It’s week 13 of your pregnancy (the last of your first trimester) and baby is the size of a peach. You can expect to see your early pregnancy symptoms fading as your placenta is taking over on hormone production.
Your baby's ovaries or testes are fully developed inside their body, and the genitals are forming outside their body. Where there was a swelling between the legs, there will now be a penis or clitoris growing, although you won't usually be able to find out the sex of your baby at an ultrasound scan at this stage.
Your baby in the 13th week of pregnancy:
- Your sweet baby is now comparable to the size of a peach but less than a finger
- The head is only one-fourth the size of the body
- The baby has start rooting in the mother's womb and has tiny fingertips
