So for the first time since giving birth to my daughter (which happened march 15), I looked at my vagina . I've been so nervous to look at it . 
I was in the shower and had my handheld mirror and looked and right inside the opening of my vagina was a small white ball/bump . It doesn't really hurt or anything , but I've never seen it before . 
What do I do ?? Will it go away on its own ??
