Jaimie....welcome to the wonderful world of AGING!!! :)
Just wait-- pretty soon you'll be plucking them from under your chin! This is a common complaint for women-- especially once they hit their mid-late 30's, unwanted body hair starts creeping up.
It's even more common for women with darker hair. Lighter heads can have this problem too-- but, lighter hair USUALLY though not always means LESS hair, and THINNER hair as well.
And naturally, the problem is worse for darker haired women because the unwanted hairs are DARK, so they are much more obvious.
It can also be a symptom of polycystic ovarion syndrome, or PCOS. Other symptoms are irregular menstrual cycle, cramping (even when you're not on your period) due to ovarian cysts, weight gain and inabilitiy to lose it, problems sleeping,etc.
If you're having those symptoms too, then you may want to talk with your OB. Other than that, it's probably just one of the symptoms of aging!
Aren't you THRILLED? :)
Happy plucking! :)
