Could it be a Pimple on my vag?

AFROditie • hello :)
So I shaved my cat a few days ago. And I had protected sex right after. And now I have this big o bump on the right side of the lip of my vagina at the very end close to my ass. I dont know if its a pimple or if its because of the razor I used. Anyone else have this happen to them before. I should add that i had a small bump in the same spot before I had sex and before I shaved. So im just curious if its just irritated or just a pimple.
