I had mine done at the age of 40. I'd always had very erratic periods, but the type of period had always been the same. I got sick in Feb 2008 and after I got sick, my periods became really weird. Very heavy with lots of blood clots, and then very close together: 21, 22, 19, 18 days (I was used to 28, 32, 48, 62, 51, 27 days, etc, even skipping a couple months at a time). And this type of cycle I'd had since I first got my period, so having my daughter nine years ago didn't change or affect my period.
Knowing this was abnormal, even for me, I saw my GYN, who did an ultrasound and found my endometrial lining was 11 mm *normal is less than 5mm*. She recommended the NovaSure. Since I was done with having kids, it seemed the best choice. She did a biopsy and that was normal (checking for hyperplasia or cancer).
I had mine done in June 2008 and haven't had a period since (one of those lucky few who end up without any). Mine was, I believe, the one where the inside is burned or cauterized. For my own peace of mind, I also had a laposcopy done to rule out PCOS and Endometriosis (none). Since I was out, I didn't have any pain, and even when I woke up, the only discomfort I suffered from was the "bloating" the lapo gas had given me. Otherwise, I don't even remember any cramping.
I've been very happy with having the procedure done. My only gripe is that I have no idea when my cycle does come, so can't track things like PMS (so can't blame bad moods on my period!) or watch for perimenopause. But I figure that's what they have lab tests for (to check for those midlife changes.).
The only thing that I know now is, certain nutritional problems can also affect your body chemistry and your period/mentrual cycle. I found this out, though, after I'd already had the NovaSure. Since I had had enough problems with delivering just one child, my husband and I were content with our family size, so we haven't regretted going forward with the NovaSure. BUT, knowing what I know now, I would urge any woman who is contemplating having this done to also search out a Naturopathic Nutritionist and discuss whether your menstruation problems could be related to a nutritional deficiency. It's said that certain nutritional deficiencies can play havoc with your cycles, and if they're taken care, your cycles will sort themselves out. It's worth looking into, I think. If I'd have known about this when I was contemplating having the NovaSure done, I would have taken a little time to see if perhaps my problems could have been solved through nutrition.
If you decide to have the NovaSure, I wish you good luck and a speedy recovery. I am soooo glad I had mine!
