I think I might have mouth herpes? Help??

I lost my virginity this past Saturday and gave him head. I had sex with another guy this Thursday and gave him head too. Yesterday, a small lump appeared on my bottom lip line and I figured it was just another lip pimple. But since I had given head to two guys, I took into account that it could be mouth herpes. The area isn't pimple-like anymore and is starting to look like a blister. It's swollen and red bc I've been messing with it all night putting hydrogen peroxide and ice on it in the chance that it is oral herpes. I went online to look up how long oral herpes would take to show if you contracted it from giving someone head and I received no answers. I frantically asked my friends and they didnt know either. One of my more experienced friends with sex told me if it was herpes, I would've seen it on the guy's penis and lip. I didn't see anything on either guy so I said maybe one of them has it but it just didn't show? Like, the virus could've been in his bloodstream/bodily fluids and that could've transferred to me when he cummed in my mouth. (I have cuts in my mouth from braces so that theory of the transfer doesn't seem too unrealistic for me.)
