Is her medication causing this?

I'm not a doctor so this is obviously just my opinion. But, what kind of medication is she on for her "girl" problems? If it's birth control she could possibly be nauseous from it. She could also be nauseous from other medications too. If it's uncomfortable for her I'd advise her to call her Doctor since she can't afford going, and telling the Doc her symptoms. Suffering isn't a good thing..
