its "trying to concieve" and some symptoms of early menopause actually show up before menopause actually starts.
I guess the menopause *could* be an option.. You still seem too young for that, but just an idea. Are you ttc?
What is your age if you don't mind me asking? I only ask because my Mother had similar symptoms and it turned out she went through menopause very early (at 36 years old.) This may be far fetched, but I just thought I'd start by offering that story and finding out how old you are.
