Thread: Yeast infection?? Or something worse??

Well, I didn't really know where to put this soo I decided to go with the 'Menstrual Cycle' category.

Anyway..
I had unprotected sex with my partner on April 28th. I know he's the only person that I've been with. But after we had sex we were talking & he confessed that he had been with someone else. So anyway, on like Monday morning I woke up & my vagina was itching really bad (on the inside, around the opening, like where you'd put a tampon). I tried to resist the urge to scratch it, but I couldn't, so I used toilet paper like I was wiping & when I did, it started burning afterwards really bad. I had never had a yeast infection before so I called my uhh ex gyno & asked her if I could just try Monistat & that if it works, just assume it was a yeast infection. So I went out that day & bought Monistat 1. I used the little insert thingy.. & when I woke up Tuesday morning, the burning was like 1000x worse then it had been. All I wanted to do was go back to sleep. So I did, & when I woke up, it felt almost 100% better. I'm also having some back pains & some cramping. Nausea.

Now here's the issue:
Every once in awhile, I get an itchy feeling down there again. Nothing compared to what it was that first day, but I do feel it. I tried to get an appointment with my gyno, but I would be a new patient & the next appointment they had wouldn't be until June 23rd.

My best friend said it's a possibility that I could be pregnant because she got yeast infections at the beginning of all 3 of her pregnancies. I know it's too early to tell whether that's the case, but what do I do in the meantime while I'm waiting on my doctor's appointment? If this does happen to be an STD will it cause problems with me waiting that long?
