NEED ADVICE HORRIBLY

Hello I hate to be a bother and I know I am gonna seem so so irresponsible but I swear this is something my parents won't help me with.

IN SHORT: Met a guy, we date, he turns out to be a huge creepo, I happen to get unlucky. I am Catholic and believe heavily in no premarital sex. My parents will not open a case about it.

I need to get a test I think, I am starting to feel tender and exhausted, I've slept 13 hours two nights in a row and I know it may be placebo but I am still wanting to be sure. I don't have money, how could I obtain a test..

So so sorry.
