Can the antibiotics for an urinary tract infection prevent pregnancy?

No. Antibiotics are known to render oral contraceptives less effective so may increase risk of pregnancy if you are taking birth control. However, they are unlikely to prevent pregnancy if you are taking a short course for a uti.
Should not. You need to check with you obstetrician if you need to be on antibiotics when pregnant. Good luck.

How soon after finishing my anitibiotics for a urinary tract infection can I have sex?

I believe anytime. Unless there is a specific issue with your condition, the type of antibiotic you are using or some very unusual problem, taking antibiotics should not preclude one from having intercourse. If a vaginal or penile condom is used, i cannot think of a reason otherwise. Take the antibiotics as prescribed and take care of yourself. See your doctor otherwise (call or return to clinic).
