Mom went through menopause a bit early, and my gyno said I may very well follow suit. I am not really sure if that's a good thing or had as I'm still undecided about having kids and would prefer being married before I try for any. That and I don't really know if I can go through pregnancy without completely losing it. I can't imagine me meds a pregnancy friendly so going it med free might be my only choice.

I'm getting side tracked here. Sorry. I think that there is no set time frame as each woman is different. It could range from barely being noticeable to being like climbing a mountain, arduous and never being comfortable temperature wise. It all depends on your body and the hormones within.
