Nevadangel...It just happened to me last December 18th to be exact. I did not have a period for 17 months and was shocked and a bit alarmed as well when I got it. I called my GYN who is wonderful. I knew what he would do before I even called and hated the thought. He scheduled me for an internal, a uterine biopsy and did the CA125 blood test. All came back normal, thank the Lord. The biopsy is uncomfortable but tolerable. I've had it done before so I was a bit apprehensive but knew it was important. In the end, he said this happens sometimes with no apparent reason. Now, I have not had another period since that date. So let's see if I make the year mark. I am 58, a bit old for this to be happening! My hot flashes are intense and he tells me it will end soon...but when?!
