So I'm 19 and since around Christmas I've been having small bits of bright red blood on my toilet paper after going to the toilet. Before this happened I had a horrible sharp pain in my lower right side of my abdomen, I went to the hospital but with covid and everything they just said get an STI check and sent me home. Everything was negative and now I'm wondering if I should go back or go to the doctors to figure out what's happening. If anyone has any idea what it could be please let me know.
