Okay so, I just got off of my period today. Yesterday I was spotting a little bit, but I still kept using tampons until I was fully done with my period. Anyways, yesterday I had a tampon in and my vaginal opening surrounding the tampon was itching a little so I decided to itch it of course. I noticed that rubbing the skin surrounding my tampon that was inside of me felt good when I rubbed it. So today I noticed that my vagina was itching a lot more and I also noticed my vaginal opening was irritated, & red. I decided to put vitamins A and D ointment cream on it. I did some research and fount out that petroleum like substances are not good for the vagina and may cause an infection. So I took a warm bath and washed off the cream with no soap, just water. I got out, I did an inspection on my vaginal opening and I noticed I have a small white bump on the right side of my vaginal opening. It hurts to touch it, and it seems very irritated. And by the way, I here recently had sex about 3 weeks ago, so I'm not for sure if it would be genital herpes so I'm freaking out. Can y'all help me out here?
