Question about birth control

Patient: How long does it take for birth control to leave your system?

Doctor: Hello,If you have been on hormonal contraceptive pills , then it loses its effect in 48 hrs.If you have been on de pot injection or progesterone IUD, then the effect may take whole 1 month after the last missed dose or removal.If its a plain copper IUD, then fertility is regained in the same cycle.In cases on implants, it takes a month for cycles to regularize.I hope i have answered your query,regards
