Wa'alaikumassalam! Ahhh, ni memang boleh jadi normal sih especially early days on the pill, body kita kena masa adjustment period, especially kalau fully breastfeeding lagi. A few of my mum friends had the same thing, period jadi irregular atau keluar banyak kali dalam sebulan when they first started, tapi settle down after 2-3 bulan. Tapi since you've already seen your doctor, best to monitor next month macam they said dan if it still happens 3x dalam sebulan, check in with them again okay, kalau-kalau ada other reasons or maybe need to switch pills. Jangan risau sangat dulu, tapi do keep track of when you bleed so you can tell the doctor clearly next time!
