Oo mamsh, totally normal! Your nipples are getting bigger and darker as your body prepares for breastfeeding, a few of us moms noticed the same thing around that time, and honestly it freaked us out a bit pero it's just your hormones doing their thing. The good news is once you start breastfeeding, you might experience some sensitivity or tenderness, so one of my mum friends swears by Mama's Choice Nipple Cream (it's pregnancy-safe and breastfeeding-safe!) para ready ka na once baby arrives, saved her life when latching started. Enjoy your pregnancy!
