Of course, there is a slight chance of pregnancy because you're having sex. No birth control is 100%. But, you aren't aware of any condoms breaking, and you're aware that he used them properly. Stress can cause your period to be late, but if you were pregnant, you wouldn't be experiencing any pregnancy symptoms just yet. It's still too early for that because you'd be around 2 weeks pregnant. You usually don't know you're pregnant in the first month, but since it's been two weeks since you've had sex, you can take a pregnancy test now and get an accurate result. Your period isn't technically late, since it's only been a month since your last period as of today. I'd wait a few more days to take a test to make sure.
