Hi OP
Do you know why your periods have become heavy? It's not a natural side effect of getting older, there's usually a cause. I had this from 44-47 and it was caused by fibroids. I couldn't cope by the end, they were just horrific, so I had an ablation (where they burn off the womb lining; winds worse than it is!), removed my fibroids and fitted a Mirena.
Six months on, my periods are now like two drops of blood. I did go through a low patch about 3 months after the Mirena where I felt sad for no reason, but I'd heard great things about it (I chose to ignore the bad things I read) and now I'm back to normal.
I think the Mirena has the lowest dose of progesterone you can get in a contraceptive, I think it's lower than the mini pill.
I was soooooooo reluctant to get a Mirena as, like you, I heard horror stories. But in the end I just couldn't cope with anaemia, flooding, clots, and dizziness every 3 weeks (lasting for 12 days), so I took the plunge. Really glad I did.
Ask your GP for a scan to discover why your periods are so heavy, though. Or a gynae appointment.
Good luck!
