I know it wasn't smart but Monday night around 8pm I hooked up with this guy and we didn't use protection. I woke up Tuesday morning around 10am and noticed I was itchy down there. I took a mirror and there was a lot of thick white discharge, and there was some bumps around my vag hole. It itches maybe half to 3/4 of the day. It's now Thursday morning and it isn't gone, nor is it getting any worse. Could it be a STD or is it too early to show symptoms? Maybe it's an allergic reaction or a yeast infection? Please help.
