did I have a miscarriage

Ok so I had sex while i was 5 weeks pregnant. idk if I was pregnant I'm jus guessing bc this test ⬇(will insert pic below) said faint positive n many other tests after that had faint positive too . anyways I had sex for like 4 hours straight n It was like rough sex like really rough. I started bleeding n thought either I started my period or jus bleeding cuz of me being pregnant n having sex roughly. idk but I bled out little clots n the blood was bright red n it lasted for ab 2 days it jus stopped like rn as I'm typing n it was like as heavy as a period

I'm confused my mom says I had a miscarriage buh I really don't feel unpregant . I fainted earlier today . idk
