Based on your first post and your replies to the questions others have posted, my advice is you find a real doctor who knows what s/he is doing and don’t take any osteoporosis meds until you get more information.

Did the doctor who prescribed the bisphosphonates for your bones do ALL of the tests listed on Dr. Brown’s website? Here is a link to things you should have checked before you take any osteoporosis meds: https://www.betterbones.com/testing/whats-the-cause-of-your-osteoporosis/

Did s/he do bone turnover marker tests? Did s/he even bother to tell you what bone turnover markers are?

Did s/he advise you to get a DEXA w/ TBS (trabecular bone score)?

Did s/he ask you if you were on HRT or did s/he prescribe it for you?

If you are answering no to the questions I’m asking, don’t feel bad, most doctors who claim to treat osteoporosis don’t do any of the things I listed above. Mine didn’t, which is highly annoying, and I had to figure it all out for myself, and by the way, I went through an extremely early menopause too. I was perimenopausal in my mid-20s and by my very early thirties, I was told I was in menopause. If I’d been put on HRT in my early 30s, I’m 100% confident that I would not have be diagnosed w/ osteoporosis at age 50 (my 1st DEXA, done at age 50, lumbar spine T-score was -3.9, hips were both around -3.1).
