17 Weeks Pregnant

Mother

At 17 weeks pregnant you'll notice your breasts have changed quite a lot in preparation for breastfeeding.

Your nipples will be larger and darker and you may notice a creamy white substance, colostrum, leaking a little. It may be time to think about getting a more supportive maternity bra!

Baby

Your baby is now producing urine. He also drinks some of the amniotic fluid in which he floats. His skeleton is changing from cartilage to bone and if you are expecting a boy, his prostate begins to develop.
