I am having surgery in a few days(bone spur removal on my ankle) I had unprotected sex with my soon to be husband(getting married in June)today I am on the pill have have been taking it like I should for the past seven months I am not sure I will be put on an antibiotic after the surgery in fact I don't think I will be but just to easy my mind my question is this: How long BEFORE taking an antibotic is it safe to have unprotected sex on a birth control pill?

Female 19 almost 20 years old thanks!
