I hope it helps you in some way. I had a hysterectomy so only use a tiny dose of progesterone and luckily don't have to deal with any bleeding issues. Yes good to start the estrogen slowly, see how you feel. I would give the P/E at least 3 mo or more first and adjust that before adding T...otherwise it's hard to know what is doing what I found. Every time you change a thing, best to try 3mo or so to see how your body adjusts. It really is frustratingly slow. I'm much younger, so probably the overall doses you would use would be much smaller. I just learned about a supplement Resveratrol, that seems to be helpful in building bone. May try it. I've been using collagen...not done a thing for me. I think people like outselves with connective tissue problems may not process or use collagen correctly. Or maybe there is some inflammatory process that is interfering. I've got the SI joint pain thing too! The muscle and connective tissue loss from aging only compounds things. For good menopause info, I like Dr Louise Newson's videos on YouTube. There's a great podcast on apple podcasts called "Dr Streicher's Inside Information" you should check out too. Dr. Lauren Streicher is US based, but covers many topics for all ages of women.
