22+5, vaginal pain?

Re
In the mornings and sometimes throughout the day I get a pain almost like in the bone under my labia. Not sure if that makes sense but it's the only way I know to describe it. I've been getting it for over a week. It's not really inside my vag, but on the outside of it. It's a sharp quick pain that lasts maybe a second each time. Does anyone know what this could be? My appointment is on Tuesday so I'll bring it up then as well. Thanks!☺
