FPA Contraception

It just wont stop :s

ive been taking the contraceptive pill for 3 months (the one with the 7 day break) i missed it for 2 days and started to bleed a little bit on te second on te third day i tried to catch up so took 2 pills but didnt want to take the third just incase. i didnt stop bleeding so decided to not continue taking the rest of them. this was from the 7th i started bleeding and now its the 20th and there is no sign of me stopping.. ive spoken to a gp& doctor but i know i should have stopped my now. i want to be 100% sure im ok and i want to be reassured .. i forgot to add i take/ took rigevidon
