Spotting and Pregnancy.

So I will be testing to see if I'm pregnant on Friday which will have been exactly 1 month since I had unprotected sex on my fertile window (like an idiot may I add, I completely forgot it was that day). But I am currently 8 days or so late for my period and I've been peeing a lot more, my sense of smell is stronger and I'm bloated a lot, I also have spotted here and there. It lasted maybe for 15 minutes and then it's stop completely. And it isn't consistent but it wasn't like any period I had ever had so my question is could I still be pregnant is that normal when it comes to early signs of pregnancy. I'm just super paranoid and I don't want to test too early. Any help would be great thanks! 😊
