STD or just a bunch of coincidences?

So I don’t remember exactly when I found the bump, I think it was Monday during the day, but I just happened to check down there, I occasionally do so because I’ve been prone to ingrown hairs recently, and I found an unusually large bump on my labia (major I think it is.) it wasn’t HUGE, probably the round part of a kernel of corn. It didn’t hurt, or itch, I didn’t even know it was there until I saw it. It was firm and I was able to pop it after a good pinch and puss came out. (Sorry for the details, I figured as much as possible would help) and blood. Later that day I was feeling achy like I wad coming down with something and the next morning (Tuesday) I woke up with a sore throat that turned into a full blown cold by the end of the day. I kept neosporine and a bandaid over the wound, I always get super scared whenever I get a bump like this, so far I’ve just had bad ingrown hairs which I know to be that because I end up with a super long hair, so I picked at it a bunch so of course it was tender & hurt a bit at touch or pressure but it hasn’t really itched, tingled a little bit that could be from the band aids being taken off and the sticky stuff irritating the surrounding skin. It’s almost healed and my cold is almost gone too..... another thing is I’ve been dealing with a lot of white discharge pretty steadily for the past year, it doesn’t smell foul, just strong, or if it dries on my underwear it leaves a strong almost bad smell but It’s not fishy. it’s thin and liquidy not like egg white consistency, the day after I popped the bump it was especially bad, volume wise, but I am about to start my period & I’ve read that that can play a part in discharge conditions.

I’ve only had sex with penetration with two people in the last year, me and my ex only did oral. I’ve only had sex three times in the last year, but all three times have been relatively recent (since about August)... so if I had an std wouldn’t it have shown up before now?

Does this sound like herpes?? I’ve done a lot of research and I can’t find anything that really matches what’s going on.... thanksgiving and over the weekend I got pretty drunk, I ate a bunch of unhealthy food which I don’t really do anymore, I smoked a cigarette lol and I spent the night at two different family members house over with only one shower between Thursday and Sunday night, so could it just have been a badly clogged pore that got irritated and my body was dealing with too much on the inside and then I picked up a bug at the bar or just from overdoing it? The cigarette thing I included because I used to smoke but I quit about a year ago but they would always make me feel like crap sometimes from just one but usually 2 or more.

I’m going to get tested, I just don’t know quite when yet, I’m not sure I’ll be able to afford it because I have an orthodontist bill to pay for. But I wanted to check around until I can to maybe put my mind to ease a bit. Sorry for such a long post and thank you if you read it all the way through!!!!! 💖💖💖💖
