Have any of you ladies out there ever experienced these symptoms?

I have been having trouble with my monthly cycles. About 3 years ago I started having two periods a month. At that time I also started having night sweats, occasional day hot flashes, anxiety and just not feeling well. For the past couple of years I have been only having a period about every 3 to 4 months. This last period I have had excruciating cramps, still having night sweats only worse than before, and still don't feel great. I m tired all the time, I don't sleep well, I wake up very early and can't go back to sleep. The funny thing is I feel worse when I have my period. I also have dryness down there. I am not as interested in as I once was. I have done some research and talked with my doctor who has checked my thyroid and for diabetes but has came up normal on all tests. I am thinking premature menopause but my doctor says no because I am only 39. I have an appt. with a gyno in a couple weeks but just wanted your input. Thank you in advance, I really appreciate it. xoxoxo
