Cervix pain at 28wks

I want to start by saying that I’ve already spoke with my dr, just not really satisfied with their answer. (Dr told me to buy a support band)

I am 28wk & 6d pregnant with my 2nd child. All of day (15+hrs) I have had a very intense, sharp pain in my cervix. I woke up with this pain so I’m not sure exactly when or why it started. It’s definitely not lighting crotch. It feels like something (baby?) is coming out of my cervix, like actually in the process of busting through. Literally nothing helps, I’ve tried sitting, standing, sitting/standing is weird positions, laying down, a bath... it just doesn’t work. My entire vaginal area is sore, even on the outside, it feels like I got punched in the vagina lol. I spent a lot of my work day just bent over tearing up.

Has anyone else experienced this and know what is going on? I told my dr all of this but based on their response I don’t think she understood where it feels like the pain is really coming from, but maybe I’m wrong. Any ideas?
