If a woman has had an ovary removed, does that mean she only ovulates every other month?  If not, does that mean she will run out of eggs twice as fast, and go through menopause much earlier?

Im curious because my girlfriend had one of hers removed at 17 because it was being a bitch (had a cyst)

No and no. Both ovaries can produce eggs in any given month, though one usually dominates in any given cycle. And menopause has absolutely nothing to do with running out of eggs, thought they are often greatly depleted to somewhere around 10,000 (from around 400,000 at the onset of sexual maturity) . It's a hormonally orchestrated process.
