I have a small red bump on my bikini line. I do shave and occasionally get ingrown hairs. But those tend to go away after a few days. But I noticed a single red bump (it doesn't itch or anything), last week and it hasn't gone away yet. I'm going to get tested in a few days...but I'm wondering if I should be worried that it's herpes?

(and, no, I have not had sex recently--3 months ago)
