Abnormal menstruation 6mos after c-section

Hi mommies, did any of u have the same dilemma as mine? Nagnormal na po ksi mens ko a month after my c-section (dec 2019). Ngayon 6 months na po mula nanganak ako. this month of june isang buwan na po ako nagmemens. heavy flow ang first 2 weeks ng mens ko then pakonti at the end of month. Marami pong buo buong dugo lumalabas sakin. Ngayong month ng july, start na naman po heavy menstruation ko. i dont feel any pain naman po. is this normal?
