am I pregnant?

Hannah
So me and my bf have had unprotected sex but he pulls out. I'm supposed to be on my last day of my period but I haven't even started.  I've have baby cramps here and there. But no period. And I e had loose stool for about 2 weeks now. I'm not has hormonal as I usually am either.  I know I'm most likely pregnant but does anyone have any other "maybe" answers.
