opinions?

My period is eleven days late, BUT 
I've also been off my normal sleeping schedule and horribly stressed. 
I've had sex, but he puts on the condom halfway through 
Today during sex there was blood on fingers and other things, but not bleeding like I normally would when my period starts. 
Opinions? 
(I'm 19 and would quite literally be disowned by my mother if I were pregnant, and she absolutely hates abortions, and I personally don't think I'd be able to have one)
