Hey mama, breakthrough bleeding is super common sa first weeks ng pills especially pag nagsimula ka lang, kaya don't panic! Since you're breastfeeding, I'd really suggest checking with your OB to confirm na okay talaga ang Daphne for you while nursing, at para ma-rule out din any other causes ng bleeding, one of my mom friends had unexpected bleeding din at turned out hormonal lang siya, pero mas peace of mind kung na-confirm ng doctor. Keep an eye sa bleeding pa rin for the next few days, at kung sobrang dami or may cramping na mabigat, go to your doctor agad ha. Fingers crossed for you, mare!
