My period is 3 days late now, which is unusual for me because it's usually on schedule. My boyfriend and I had sex maybe 2 weeks ago and we used a condom like always. I haven't had cramps or any other normal symptoms of my period. I just need some advice on this. I'm hoping it's just stress because I just got an apartment and work has been stressful the past couple of weeks. I'm really starting to get nervous about it.

Using protection only reduces the chance of pregnancy.. it never eliminates it.

However with that said... lots of things can make you late... I'd wait a while longer then test because you might find your period will come in the next few days.
