She started birth control on the 2nd to last day of her period which was on a sunday we had unprotected sex on a Thursday and i came in her she took the pill that same day at 9pm which she always takes. Im worried she might get pregnant because we didnt wait a week for the pill like recommended . what u dont get us if she already took the pill for 4 days why can't she be protected isnt that enough hormones to stop a pregnancy? What should i do ? Will taking plan b help? Shes still on birth control by the way hasnt missed a pill.
