The doctor put me on mononessa about a month ago.. I go on and off and im on my first middle pill (The dark one).. a week ago i was off and had sex then came right back on now im bleeding very heavy and everytime i bleed a clot comes out.. sometimes broken up and sometimes huge.. i also cramp now.. is it because i had sex that im bleeding like this is is the pill doing this? When will i get normal?
