Sore On Vagina After Rough Sex (NO PICTURE)

So me & my boyfriend had really rough drunken sex. We used a condom but it might have broke. I can't really remember. The morning after I noticed a sore only on the inside left side of my V. It's a tad bit painful to the touch but not extreme. It kind of looks like one of those Kanker sores you get on the inside of your mouth. Could it be from the rough sex or a scratch??? Has anyone had anything similar happen? Did you do anything to clear it up quicker??

PS I'm not worried about STDs I use condoms and me and my boyfriend got checked last month just in case.
