Possibly pregnant? (Please help!)

Hi everyone! I want to start this post off saying please no hate. I know this is probably a dumb question but I really need advice. My period was a few days late. I was more irritable than I ever have been in the days leading up to it and I felt so off. Now that I finally got it, it’s the heaviest and most painful period I’ve ever had. There are so many blood clots and I’ve never had so many. When I woke up this morning and used the bathroom I saw a blood clot about the shape and size of a large grape. I know this could just be normal and I’m not used to it, but I’ve seen people joke about their blood clots like this. I was just wondering if there is any truth to that and I could have been pregnant. I have protected sex (condoms) but there was one instance a little while ago where he went in raw for a couple strokes and then put the condom on. Any advice or information would be wonderful!
