Possible miscarriage?

This happened to me April 22nd, it happened at night time I went to the hospital. They thought it was a miscarriage and sent me to an OBGYN. He didn’t even look at me, or look at the pictures that I made. I waited an hour just to get told it was my uterine lining and to have a nice day. I think it’s much more, because when it happened the next morning I took a pregnancy test and it had a faint line. I also feel like it was, or I could be crazy. What do y’all think?
