Hi.
I think it's worth a try. I tried it for 10 months... Lots of different ones. I'm same age. Unfortunately it hasn't worked for me.
I had a call with the meno clinic, and that is what they recommended trying first at age 44.
I now have a prescription for hrt... Yet to start.
Sorry, no advice on the breast cancer issue, but like you, I'm at my wits end. I need quality of life....
There are low dose estrogen ones. There is also the progesterone only pill, similar to mirena, but pill obviously, so more control.
I never got around to trying qlara. Tried everything else near enough 🤣.
