Nanganak ako 5 months ago. 1st menstruation ko after delivery nung 4 months ung baby ko. Date nun was January 19-27. Bale 9 days. Tapos dinatnat ulit ako after 10days (February 7-9). Tapos dinatnat ulit ako a week after (February 17-hanggang ngayon meron parin feb 19). Normal ba to? O kailangan ko magpacheck up?
