how likely am I pregnant ??

I am on birth control and have been for almost three years and take it religiously. In May I was on Ciprofloxacin for three days and had sex one of those days on May 24. My boyfriend always pulls out. It technically would be after my ovulation days and I’ve had my period since than (kinda short but I’ve been extremely stressed). Is there any way this could make me ovulate now and cause me to be pregnant since antibiotics affect the pill or am I in the clear? I’ve taken a few tests they say negative but my anxiety has been killing me and I’ve been feeling off.
