Hai! Okay so fully breastfeeding memang boleh delay period or even skip it for months, especially kalau first period balik after 6 years, hormones still settling lah, so 2 weeks delay is pretty normal lagi. But the degupan feeling kat perut tu kena check dengan doctor juga, sebab tu bukan typical breastfeeding side effect, better safe than sorry, especially since you haven't seen a doctor about it yet. A few of my mum friends also experienced weird sensations postpartum and turned out it was just gas or uterus contracting, but they all got checked to be sure. Go lah to clinic, just to put your mind at ease, at least know what's happening with your body. Mana tau?
