Given your prior things, it may be related (endo, etc.). That said, I was your age when my symptoms started. It makes sense, since I officially was done at 48, ten years later. I had horrible PMS, which got worse as my periods got closer together. I wasn't having any real menopause symptoms like hot flashes until I was about 45-46. They did not bother me as much as having my period every 3 weeks. I hated that whole thing from the minute it started... pms with horrible physical symptoms, cramps the first day. When the periods got irregular, like not coming that often, I was thrilled.
