I'm 52 yrs and peri-menopausal. I have two fibroids, each the size of a small satsuma (one of which is embedded in the uterus wall). Basically, suffered truly hideous periods, pain, flooding and bloating for years (Live in continental Europe where I am being treated.)
Like you, I was offered the Mirena coil, but owing to my wierd uterus (divided and hanging backwards) they couldn't fit it properly.
So I was offered a very low dose pill that transformed my life! Although possibly not ideal at my age (although ob/gyn said some benefits outweigh some of the risks).
Obviously, I have my bp tracked regularly and regular internal ultrasounds to measure the thickness of the uterine wall and the size of the fibroids.
After several years of being on the low dose pill, we are at the point now, where in 10 months or so, my ob/gyn (after examination) will ask me to come off the pill, have one last period and then I hope to be going in to the menopause and be free of bleeding forever more.
I've had mixed responses though about whether fibroids continue to cause problems after the menopause or not. My ob/gyn says that in general, except in a few patients, they tend to shrink and not cause problems. I've friends who've said differently though!
Hope you can find a soluton that works for you! Fibroids are hideous!
