Help - I’m 16 and immature and made a mistake

I’m on day 24 of my cycle

They’re 32 days long and very regular

I had unprotected sex day 9

I just finished ovulating according to the app, I know it isn’t always accurate, and for the past three days I have had EXTREMELY heavy discharge then today I had moderate spotting that I’m terrified is implantation bleeding. I know the only way to know for sure is to take a test but I have no way to get one.

Please don’t be too harsh. I know I made a mistake and I feel like shit for it so being mean (not firm or informative, mean) isn’t gonna do fuck all because it’s too late. I just need help. (Sorry if that’s mean to say lmao, I’m not in the right headspace right now)

What the hell do I do?

Edit: My period came 11 days early so all is well!
