and I've just turned 40 - could I be perimenopausal? I don't understand why I have sore boobs and shouldn't be due on for at least another 2.5 weeks (or thereabouts - not long finished my period). I'm eating to the point of nausea (especially chocolate). I'm not having sex, so I know I'm not pregnant. Could it all be starting already? I get really hot in the morning sometimes too - to the point that I could sit in a bath of ice! But it's not all the time. My periods are also really light now. It all feels a bit odd but I'm aware I'm getting old now. I thought you were also supposed to lose your libido at this stage in your life?
