So I have been on ortho tri-cyclen lo for a couple of years now. I have always been very careful when taking a course of antibiotics (generally amoxicillan.) However, last night my boyfriend and I were having sex, and while we were using a condom, it happened to slip off inside me. We were able to get it out after a few minutes, but I just worry a bit. The pill is generally my only use of birth control. I was on a seven day treatment of antibiotics and finished the bottle on Thursday evening. Should my pills from Friday and Saturday protect me, or should I take EC?

Thank you so much!
