I am on the pill and was taking antibiotics for a sinus infection, I finished the antibiotics about 5 days before having unprotected sex 2 days apart. He didn't cum inside me either time but I'm worried i might be pregnant or have an STI?

Hi,
Welcome to ehealthforum.
Few antibiotics can affect the efficacy of the birth control pills. Chances of pregnancy cannot be ruled out as you can get pregnant even with pre-cum if you have egg present in body close to time of unprotected intercourse. Visit your gynecologist if you have any new symptoms developing indicative of pregnancy or vaginal infection.
Take care.
