Am I pregnant or am I being paranoid?

Stephanie

So normally, my breasts start getting tender a week or two before my period. Within that week, my boyfriend and I had unprotected sex.. like the entire week.. everyday. I noticed earlier this week that my boobs aren't tender anymore and my period is a day late now. My periods are normally super on schedule and come the day they're supposed to. So now idk if I'm just being paranoid or if there could be a fetus in me!?HELP!
