Like one of the other posters said, fluctuations can be a sign of perimenopause (but not always). It can last for years, and come and go. It's based on the hormonal fluctuations that occur. I started doing acupuncture twice (I started 4 years ago, then stopped, and then started it again last summer), and the fluctuations ceased for me, twice. It brought my FSH down slightly, but it's still borderline (10-12). I am 39 w/ AFC of 2-7.
How old are you? What's your AFC?
