If you are oestrogen deficient, then using HRT at your age is crucial. If you are fine using progesterone all the time then there would be no benefits for you to use a sequential regime. If, however, you were getting progesterone side effects (as some women do) then staying with a sequential regime can be preferable. I suspect the doctor you saw on a blog was referring to peri menopausal women who are likely to experience problematic bleeding on a conti HRT regime. I think there could also be a psychological benefit to having a monthly bleed for some women who have had premature ovarian failure.
You might find that having a Mirena fitted would be a good way forward for you - this usually gives fewer side effects overall, you don't have to remember to pop pills and you could simply use oestrogen patches alongside to give you the oestrogen.
I know many women find Utrogestan really good but it gave me more side effects than any other form of progesterone, especially used continuously. See how you get on with the 100mg per night and if this works for you then stick with it.
BTW - HRT for you is not just to protect your bones but also to protect the connective tissue in your joints and also maintain skin, muscles, bladder function, immune system etc. Oestrogen is a vital hormone for the body and without it many things suffer. DG x
