Possible tmi please help!!

Ok ladies, I've googled and can't find my answer please help! Earlier this week after traveling I become ill. I was vomitting and had to constantly go to the bathroom (#2 :/) and this lasted for a couple days. Well now I noticed toward the top of my vagina, really around my "pearl" is very sensitive and sore to touch. Nothing else hurts and I have no itching or discharge. I was wondering if the excessive cleaning I was doing because of my frequent bathroom trips could have just caused it some irritation? I've never had this issue before but it is bothersome.. Especially when I attempted sex with my husband tonight while vaginally didn't hurt if his penis touched or rubbed me there it was uncomfortable, almost dry feeling. Any one else have this issue ever?!?
