i am about to go pick up some antibiotics for a lingering sinus infection and i had a question. now, i know while i'm taking it i should use a backup method just to be safe, but this morning i had sex. should i wait to take the antibiotics? i'm just concerned because i thought sperm could live for a couple of days in the cervical fluid. but then again, even if the birth control was less effective would i immediately ovulate?
any help is appreciated! my google fu is failing me this evening.
