Wah this is super common la especially on the mini pill (Noriday) while fully breastfeeding, hormones still boleh jadi unpredictable for a few months after caesar! The spotting and short bleeds you're describing sound normal, tapi I'd check with your gynae or clinic just to be 100% sure everything's healing well, especially since you're only a few months postpartum. A few of us on the mini pill habis confusion nak mandi wajib jugak, honestly if you're unsure and it's just light spotting (tak macam proper period flow), most of us just go ahead and do it, tapi better to text your ustazah or gynae together-together untuk clarity on what counts as period vs spotting, boleh? Take care, mum!
