Wa'alaikumassalam! Ahhh normal je tu, don't worry! During pregnancy your nipples akan menjadi darker (macam coklat gelap sikit), membesar, and sometimes a bit sore or sensitive, especially first trimester. Some of us juga akan keluar clear fluid tu from the nipples as early as second trimester, it's colostrum, yang akan jadi susu later on. The areola (bahagian gelap around the nipple) akan expand and may develop small bumps, but semua tu normal changes preparing your body for breastfeeding. Come third trimester memang rasa lebih sakit lah if the bra tidak comfortable, so banyak mummies recommend maternity or soft bras je yang tidak ada wire. It'll all go back to normal eventually after you're done breastfeeding, so tidak perlu khawatir sangat!
