I will be 48 this month. Two years ago I missed 3 periods in a row and then started back as normal as ever. Every 28 days. I've been predictable since I started at 13. I've never missed a period outside of my 3 children. No situation has ever changed my cycle. Now, exactly 2 years to the date almost, my period was 45 days apart last month and I missed all of May. I'm having a lot of hot flashes/night sweats and cold flashes too. I'm cold most of the day. It's constant. I've been having the night sweats for a few years but mild. Eating and drinking affects them. I know how to control them. I have no control with these new hot flashes. I also have pains in stomach that made me think a cycle would come, but nothing. I'm wondering if I am in late transition of peri or if my estrogen has just dropped so much that I'm having a major thermostat problem. Could it be menopause?
