D.H.
Sounds like the beginning of Menopause to me.....and it's a rough ride.........I had a period for over a month and a half.........they finally had to give me something to stop it.........it was awful............
I would suggest a trip to your Dr. and make sure nothing else is going on.....just to be safe, and even if there isn't, she might be able to help you figure out something to make things better.
Good Luck and hang in there.
