I was put on amoxicillin

Hi all! I was recently put on amoxicillin for 14 days for a sinus infection. They put a note on my prescription saying it can interfere with my birth control and to be careful. Does this mean I can’t have sex at all while I’m taking the antibiotics? We always use a condom during sex so if we use a condom will I be perfectly fine? I can not end up pregnant, not the right time for me or my boyfriend. But it is his birthday next weekend UGH!
