My period is late!!!

Daelyn
My period is 4 days late, i was supposed to start on Monday, I have a 32 day cycle & my period haven't ever been this late before. But my boyfriend & I did have sex 2 weeks before my period was supposed to start but he would put it in but we would stop before he ... & put a condom on & then continue.....but I did take a pregnancy test the first day I missed my period & then I think Wednesday I took another both were negative. But I did get the tests from the dollar tree. Idk if those are good tests. But I just wanna know if I could be pregnant but I doubt it...
