Hi, I am only 17 and I have noticed for about 4 years now I have been getting a bump on the inside of my vagina it's on the right lip and its not really painful just when I touch it . Also, it only comes 1 at a time and it is only there for about a week then goes away for like a couple months and then comes back. It's a shape of a oval and its Bairly noticeable . I went to get it checked but she said it was fine but I also went when the bump was gone. I feel like I do have something wrong what is it?
