Am I pregnant or being ridiculous?

ch

Okay so. I had sex on Tuesday and it was unprotected and ended with the other person cumming inside. It’s Sunday night and I’m five days late for my period and yesterday I had something like implantation bleeding but it also may have only been spotting? But it was only for like an hour yesterday early evening and I haven’t bled at all since. I’m being ridiculous right? Like. That’s way too soon? I’m being totally ridiculous, right?
