My boyfriend & I had sex unprotected two days before my period was supposed to start . He pulled out & then came . But I'm not sure if any precum came out before he pulled out . Is there a chance I'm pregnant . I read that stress can cause a late period & I've been stressing about finding a new job . I'm feeling all the symptoms I normally have when I'm pre-menstrual . So am I late or pregnant . My period was late before but Thts when I was irregular & a virgin at the time. So I had no reason to worry about being pregnant .

Just late most likely

Just late most likely

I'd like to see the articles and studies to back up your answer.

Fact is, any time you have sex pregnancy is possible, so no, it's not "just late most likely". There is a chance that you're pregnant. There's plenty of sperm in pre-ejaculate to get the job done, and you had unprotected sex.

Have you tried a pregnancy test? That would be the next step.
