Am I pregnant

I need advice because I think I'm pregnant.I'm17years old and2days late.I've been having headaches,back pains,nausea,tiredness,appetite,mood swings,cramps.My parents don't know that I have had sex and I can't buy a test.Am I pregnant?Is there a way I could find out?

Why can't you buy a test? The name brand ones can be expensive but the dollar store carries pregnancy tests. Are you on birth control? You coould always go to a planned parenthood for a test since the will do them for free.
