Not sure what group to add this to?

I really was hoping that I was pregnant because my boyfriend and I had sex three times and each time he pulled out. We weren't TTC but the idea of a baby makes us happy. I started cramping and had some boob soreness but it's too early to test. Well this morning I woke up with itchness and burning down there and now I think I have a yeast infection and I honestly don't think I'm pregnant anymore and it really bums me out.
