So I'm in a long distance relationship and in July my boyfriend came up to visit with me and ya know we love each other so one led to another and we ended having sex. we did use condoms but I am not on birth control because that was my first time having sex. So my August period was really late and it was not heavy at all. my normal periods aren't ever that heavy anyways but they're normally on time so that made me panic a little because that's just how I am. But anyways flash forward to now my period is 5 days late. could I be pregnant or am I just stressing out? please help.
