I heard you can get increased facial hair growth with bc pills?

You heard right! Yes, it can happen, with certain bc pills with high hormone contents. Your gynecologist can change you to a lower-level pill. But there are lots of other causes of facial hair growth; don't assume it's the pill without letting your doctor rule out other causes.
Not with Estrogen . In bcp's that contain estrogen, the hair growth would decrease not increase. Bcp's have long been used for the treatment of hirsutism often associated with pcod. It doesn't really matter what pill is used, the hair improves. If the pill is Progesterone only, or Depo-Provera provera, (medroxyprogesterone) then hair growth could worsen significantly. Otherwise, correct to assume underlying horm problem just worsening on pill.

Has anyone experienced increased facial hair growth with oc pills?

Not Really. Bcp's provide hormonal changes that would decrease not increase hair growth. They are used for this purpose to treat polycystic ovarian syndrome, pcos. The only mechanism for you at age 46 that you might see increased hair is if your inherent estrogen production was way down due to age and in the pill free(cycle) week the androgen to estrogen was high. So if no bcp's you would have more hair. Read more...
