I had been spotting off and on (mostly on!) since the end of August. I'm 52. It would go into what seemed like a regular period then taper off again and then spot, spot, spot....
I found out my progesterone levels are waaaaaay low & I'm estrogen dominant. I've been taking natural supplements from my holistic doctor, following the anti-estrogen diet and using ProGest cream. Although I'm afraid to be too optimistic, it's now been three whole days of NO spotting. Finally. I hope it lasts.
Several other ladies on this forum have experienced this, too, so for some of us this is completely normal.
