AF or pregnancy?

Hi, so I’m apparently 10 dpo based on this app and Ovia. I’m aware that apps aren’t accurate but I don’t check when I ovulate or not. I’ve been having protected sex and make sure that the condom doesn’t break or anything. However, at around Monday and Tuesday I checked my cervix position and realized bright red blood. I’m not trying to conceive so I assumed that it was my cervix being irritated and telling me to leave it alone so I did and the bleeding stopped. Before Monday, I was expecting sore nipples which have now gone away. I do have a couple cramps here and there. I also have intercourse on my suspected ovulation day but didn’t think to take a plan B since it was protected. However, I did get a bit nervous with the blood coming from my cervix since I was still a week or so away from my period. My cm has now gotten more dry but I don’t have any other symptoms of my af coming or being pregnant. So I’m not sure what this is, I bought pregnancy tests just in case.
