I'm 32 weeks as of yesterday. about 3 days ago now I started experiencing pain around the opening. It's not severe its just super sore and especially noticeable when I stand on one leg or go upstairs or something like that. It's not round ligament pain because I always feel that up near my cervix. this is straight up vaginal pain and it totally blows. It feels like it's either the muscles or there might be swelling. I have not been having sex or doing anything of the sort. it just started at random one day and it sucks. Does anyone else have this or know what it is or how to stop it?
