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.
