I'm a single mom of a 2yr old and I haven't had sex since I gotten pregnant. That changed 3 weeks ago when I had sex with my child's father. Like a true dummy I didn't use protection and for almost the last week I've had painful sores develop on my vagina. It's painful to pee and the only way I can do it is sitting in a basin with warm water. I'm afraid that I have herpes. The sores are red and crater like with puss oozing from them (sorry for the gruesome image). Help?
