Mak, saya tahu ni stressful lah especially after what happened last time, tapi good news, nipple soreness waktu pregnant tu normal je, hormones lah yang buat sensitive. Yes, you can pakai nipple cream masa pregnant, and Mama's Choice Nipple Cream is pregnancy-safe and breastfeeding-safe (banyak of us use it from pregnancy onwards), tapi sebaiknya check dengan doctor atau midwife you first especially since you're in your second trimester, they might want rule out anything else or just reassure you it's hormonal. A few of my mum friends had the same thing and it settled down, so hopefully yours will too, and the cream really does help dengan the discomfort.
