So I just recently got over a UTI (I finished taking my antibiotics one week ago today) and I wanted to see how long I had to wait to have Sex without a condom because I'm aware antibiotics mess with your birth control pills. I'm on Trinessa, and me and my boyfriend were planning on having sex in two days (valentines day❤️) and he's been asking if he can cum in me. We're probably going to use a spermicide as a back up birth control methods but I'm just wondering would I be safe? How long do you usually wait after taking antibiotics to having sex without a condom again?
