Oh, those pelvic fractures are brutal, sorry that happened. And you were just trying to be proactive!
I went through menopause at age 52. Took HRT for 2 years, then the Women's Health Initiative released (prematurely) their erroneous data on estrogen. I wasn't having a lot of symptoms, so I went off the meds. Then nothing until my spine fracture. I am sorry now that I quit taking the HRT prematurely, but it seemed like the thing to do at the time...

A book I really recommend is "Estrogen Matters," by Avril Bluming, MD. It covers all sorts of issues, like breast cancer risk (not that much for most people it turns out) and heart disease. He was motivated to study osteoporosis more after his own mother broke a hip just standing on the sidewalk.

I had gone to see an ObGYN who had taken over for my previous one. This was a youngish guy in his 30s. When I told him I had restarted the HRT, he wasn't happy, saying that he had seen too much cancer from it. But most breast cancers these days are gotten into remission or cured. And if you break your hip? You have a 30% chance of dying within a year due to becoming deconditioned, infection, etc. I told him that if I ever had to choose between my breasts and my skeleton, I would choose my skeleton.
