Miscellaneous
When I entered my late 30s, I started to have weight gain (even though my eating habits hadn’t changed). Then I started to have trouble sleeping. And then later, my menstrual cycles became heavier, longer, and more painful. It didn’t know what was going on. If you are a woman between the ages of 35-50 and you start to have similar changes you may be entering perimenopause which is a time of hormonal change before meopause.
