hi im 24, had 1 child.

i have got hair everywhere except my armpits. i have never had armpit hair.

i have been to the doc and they laugh.

any help would be appreciated

Well I don't know what to say other than I wish I didn't. Why is it bothering you? Apparently your doctors don't think it's a big thing or they would have said so. Try to think of it as a postitive thing.
Enjoy not having to shave your underarms. Don't you wish it was your legs as well?
Take care and have a nice day.

You're lucky. People are different genetically. You just don't have armpit hair. If I were you, I'd count my blessings. One less hassle!!
