About a week ago, I developed a painful spot on the right side next to my vagina, on the labia tip. Then I developed a horrible pain near my clitoris. After a self-check, I found white sores that have since spread out in the surrounding area. They are flat, with no pus in them that I can tell. In fact they resemble the sores I get in my mouth when I get an infected cut, flat and white, with no pus. It's very irritating, painful and itchy. I also have a whitish-grey discharge that doesn't have a scent like yeast. I'm pretty sure it's some form of vaginitis, but I don't understand the sores. Any help would be much appreciated. I'm going in for herpes testing, and I am also five months pregnant. I have been in a monogamous relationship for 6 months now and he has had no signs of any STDs or cold sores or anything like that. Just looking to get a handle on what the possible culprit could be, since herpes would be a devastating thing.
