Menstrual Cycle

Mababago ba ang menstrual cycle kapag twice nagkaroon ng withdrawal bleeding? My last menstruation was April 4-8 wala pakong pills na gamit nun. Regular mens. Then nung nag take na ko ng pills, nag bleed ako ng April 14-16 & April 25-27. Idk if magkakaroon ako ngayong May. Let me know your insight mommies! thank youuu
