Girl question! kinda embarrassing.?!

I've included a picture of the vagina-- the hymen is right around your vaginal opening. A vagina is usually a pinkish color, though some women are more brown and, of course, skin coloring can change this slightly.

Usually pink, even with darker skin tones. I really don't know what the bubble is but my friend had the same thing and we share eachothers diaries and tell eachother EVERYTHING, such as the first time we used tampsons....ohhhh....now I remember, a friend of mine had a tampon got stuck "down there" for almost a month October 27-Nov. something, it smelled nasty and when she got it out she said that she had a bubble down there that was soft. Did that happen?
