Oo, nakakaranas din ako nito during pregnancy, lalo na around 20 weeks! Isang friend ko rin na-experience yan at sabi niya super annoying talaga, parang hindi mo maiwasan ang scratching. Usually it's just the skin stretching and hormones doing their thing, pero if it gets really painful or may discharge na nakikita mo, mas okay pang i-check with your OB para sure lang. In the meantime, a few of us swore by Mama's Choice Nipple Cream, it's pregnancy-safe and breastfeeding-safe, and grabe talaga, relieved agad ang kati at soreness, sobrang helpful lang during those months. Drink lots of water din and try to avoid tight bras kung pwede!
