blood clots but no liquid blood?

I'm currently having a late period but whenever I pee, it's almost little to no liquid blood visible but there are a lot of tiny blood clots(which is normal for me, I always have them on my periods). I've researched a bit around the internet but the only thing I could find is that it's a failed pregnancy. I'm still a virgin so this bothers me quite a bit, anyone knows what this condition might be?
