This is unrelated to the original question but...I have fibroids and ovarian cysts. Although I got periods on a regular basis they were very painful and extremely heavy. I started depo provera early last month because my doctor thought it was a good idea for me. I have been getting chills and night sweats (to the point where my sheets and pillow is wet). Last night I started a period (41 days since my last "real period," although I have been spotting everyday in between). I had a hard time staying warm last night and when I finally did get comfortable I started to feel like I was on fire. I pretty much alternated between chills and hot flashes all night and then I kept sweating. I am not sure what this is related to but has anyone experienced this?? Also, I notice that I sweat a lot when I'm working out, more than any other woman at the gym. It just occurred to me that this might be related to pcos. Any experiences with that??
