Bleeding after masturbation

So I haven’t had sex/used a toy in a few months... I just used a largish dildo and felt like I was pretty wet. When I finished there was a lot of blood both clumped and free flowing for a while. I felt a twinge/pain at one point so I think I might have just hit my cervix/it’s been a while.... I’m just a bit worried about how much blood there is. I usually bleed just a little bit when I masturbate/have sex cuz I like it a little rough, but this was a lot of blood comparatively to past sessions.... should I be worried?!?
