Birth Controlled: How long have you been together? If it's long enough for the spark to wear off, good luck getting her to change. I say that as a woman who's been in your gf's situation. It'll probably take the high, feel-good rush of hormones of a new potential romance to get her to the doctor (yes, everybody is different, but I'm not sure you should stake your happiness on a very slim chance that she'll come around on her own). Just my $0.02.
