Help!!!

I’m in college, a virgin, and I had my period about 2 weeks ago. My period is super regular and always on time. I pooped, saw a red little thing but didn’t think anything of it. I later went to the bathroom and started bleeding, and I have abdominal pain, maybe cramps? My pad didn’t really have anything on it but when I went to the bathroom, barely any pee came out but a lot of blood did
