I don't think you have too much to worry about. I assume you're not on birth control pills, as you said you guys used condoms. Before I was on the pill I never knew when my period was going to come, and sometimes it would be late, so that could be why yours is late. Stressing out about it not coming can also delay it. If you're really worried, or start to feel like you're showing symptoms, take a test, and rest easy.
