Sex and Antibiotics Pregnancy risks

[Marcia83]

I had unprotected sex one day before my period started. I am on birth control pills. I immediately started taking antibiotics the next day
after sex for a UTI. My cycle did come on while I was taking the antibiotics, but I did have sex one day before it started, and my period was about to come on anyway. Is there a chance that pregnancy could occur under those circumstances? I know antibiotics can affect birth control, and I have read that sperm can stay active for about 5 days in a woman’s body, so those are my concerns if the antibiotics affected the birth control that was in my system after having a possibility of sperm still there.

I know I answered this on another forum.  How did it go?  Not pregnant, right?

Yes, you did answer this on another forum. Thank you! I figured this forum  wasn’t as active as the other one so that’s why I posted it twice. My cycle came on, and I’ve never been so excited about my cycle coming on than that day! Lol! I want to have children, but with the right person when I’m married. Again, thanks for your help.
