I took it for years starting at about age 45 (slightly higher dose, 1.5/30 because of breakthrough bleeding on the 1/20 dose). Same problem as yours, heavy debilitating periods. With the MD's OK, I began taking it continuously.

It was very effective and a great relief not to be bothered with the horrible periods. Only side effects I really noticed was a reduction in (excess) body hair. It also smoothed out my moods quite a bit.

I took them until age 53, when I finally had a hysterectomy (why did I wait so long? <shrug>). Turns out I had "adenomyosis" which is a type of endometriosis restricted to the uterus rather than spread out all over the abdomen.

If you're done having kids and really don't want to put up with the periods or the pills any more (adult diapers, vicodin, that kind of thing), it's worth following up with your MD and/or OB/GYN. I wish I'd done the H decades ago, it made a huge improvement in my quality of life.
