Herpes Doctor

So last night i went to this party and made out with a girl. She didnt have anything on her lips and we frenched for a bit. This morning, i woke up, and there was this kind of white/clear bump on the inside of my lip. I kept feeling it with my tongue, and it was definitely not there yesterday. A little while ago, i went to the bathroom to look at it, and i squeezed it. It popped, like a zit. Weird stuff. Now its mostly deflated. No blood came out, just pus i guess. There were red marks around it before i popped it, but it didnt bleed. I put alcohol on it and all around my lips and mouth and ive been spitting for the past hour. crap. is it herpes? please somebody let me know asap!!!

i was also sharing cups and drinks with other people at the party. I dont know if it could be from that or from kissing, but im super paranoid now and i keep feeling for bumps and sores. The zit or whatever didnt hurt at all except for when i very first tried to pop it when i saw it. The second time, when it actually did pop, i didnt really feel anything...except for nervousness.
