Eh, biasa lah tu actually! Kalau miss satu dose je, hormone dalam pil tu drop dan trigger bleeding, it's like your body thinks cycle reset. A few of my mum friends ada experience yang sama, especially if they missed the timing or took it late. Better check with your doctor or clinic pasal the best way to take it consistently (same time every day helps!), because kalau pattern jadi irregular, might affect effectiveness for contraception jugak.
