How long does ortho tri cyclen (ethinyl estradiol and norgestimate) birthday control take to be effective? i started the packet on the 3rd day of my period on a wenesday

A doctor has provided 1 answer

2 weeks: You should use backup contraception ( condoms and spermicide) for the first two weeks when starting birth control pills. Remember, though, at the pill protects against pregnancy, but not against STDs. Contunued use of condoms will reduce the risk of STDs.
