Vagina pain??

Even when I’m not on my period, for the past couple months I feel almost constantly like I have gotten kicked in the vagina...?? It’s not burning, stinging or like shooting pain but really just aches all the time. I’ve taken 6 tests and all were negative and I’ve had two periods so i basically know I’m not pregnant, but what could be going on?? I know also that I have no std’s or anything like that, so I’m not afraid of that. Is this a normal thing because I’m confused and freaked out!? Is there a chance I could still be pregnant somehow and my vagina is widening or something?? I’m scared babes😭
