Is My Cervix Falling Out???

NEEDING ADVICE! Please share your experiences or your thoughts.

So about two weeks ago my boyfriend and I tried to have sex but he could barely get halfway in due to something blocking him and hurting me! It was like he hit a brick wall that shot pain all throughout my lower abdomen. We were concerned so we stopped and he started feeling around with his fingers saying something was hanging low inside me. (His exact words “I think it’s an organ falling out” 😂) I also checked and I couldn’t quite tell what it was but I guessed it was my cervix hanging down about 3 inches from the opening of my vagina and I thought it might go away. At this time I was ovulating. A week later we tried to have sex again and had the same issue! This time the pain was worse, almost a stabbing pain inside my vagina and throughout my abdomen. The pain continued off and on and increasingly got worse as my period came. Today I started my period and tried to insert a tampon but was unable to insert it fully due to whatever is hanging so low inside my vagina. I’m having very painful cramps and I’m passing huge clots. Not sure what to think and I’m getting worried! Tried to do some research and the only connections I’m getting are uterine prolapse or pregnancy. I thought it might be unlikely to have uterine prolapse due to me only being 18 and never having kids but I do struggle with endo. I also thought it unlikely to be pregnant since I’m on my period.

HELP 😅

** Update ** I have a doctors appointment for the 21st and I took a pregnancy test today which came back negative. If anyone still has any insight I’d be happy to hear!
