Mini Pill

Grace • Divorced and a mama to a crazy little toddler!! 🎀👑🎀👑

So I took the combo pill before pregnancy and baby, but since I’m breastfeeding, I have to take the mini pill. I’m wondering if different brands are different from each other because the one I’m currently taking makes me cramp really bad and I have not had a period yet. I’m 11weeks pp.
