Help... Basically...?

I've missed my period by a week and I'm bloody terrified. I had unprotected sex 3 times in a row about a month maybe more ago. I haven't done a test but I feel like I just know if you Understand me. The only problem is (and I understand some will be against what I'm about to say completely but given my situation it's acceptable) I don't know where to go to help understand my best options. Alittle advice from anyone would be greatly appreciated as I am sacred as hell!!
