Gritty period blood

Bridget

Hi so um.. I have had irregular periods for as long as i can remember. But this cycle that I’m having now is a little weird. I am spotting and having light bleeding but I noticed that my blood is gritty? It also hurts down there a lot. I believe i have a uti. I’m not really sure what’s going on. I also just lost my virginity a few days ago. And i tried googling whats going on down there, the first thing that pops up is pregnancy, so I’m kinda really freaking out lol... anyone ever had a gritty periods before?
