Should I be worried?

I am 8 days late for my period and my period does get late on the regular, occuring after 30-50 days. I even missed a whole month.

My boyfriend and I had unprotected sex but it was on my last day of my period and he didn’t finish whatsoever.

I’ve recently took doxycycline hyclate, maybe that’s what has been delaying it? Last month I’ve been sleeping 4-6 hours each night and eating less and less.

I’m not sure if I should be worried but some advice would help. I’m aware “every time we do it, there’s always a chance” but is my situation that bad?
