Good to call the GYN, or just regular Dr. You are kind of young for hot flashes.

My friend in her 50's who has really bad hot flashes from menopause is just drenched in sweat - 2 or 3 sets of nightclothes a night -- are yours that bad?

Night sweats could be so many things, as could changes in your period.

I have found that being much fitter from biking changes everything including my period and body temperature issues - maybe that's it.
