Your heavy periods could be from Perimenopause since you're in your 40's.Definitely something worth talking to your doctor about.

When I was going through perimenopause I had lots of flooding.I went the "natural" route and didn't have anything done for it and didn't take any medications but if I had it to do over I would have instead of suffering needlessly.

My doctor had suggested an endometrial ablaton and said it would make my periods very light or stop altogether.I chose to not have it done(wish I would have) but some friends said it was the best decision they ever made.
