Ss about two weeks ago my boyfriend and I had sex for the first time. I'm not on any type of birth control, but he did use a condom. He never ejaculated in me. I'm super scared I might be pregnant. I've been having random cramping and my period is 2 days late, but I don't have any other symptoms of pregnancy.  I don't keep track of my periods that well and I'm wondering if I shouldn't be worried.

I'm also experiencing a lot of stress from work, school, and home life. Could that be the main reason why I am cramping a lot and that I have missed my period?
