Me again !
I bear news regarding the F7 fiasco 🙄
The latest communication I have received from Thera (after much pestering) is that FemSeven Conti has not been discontinued, they anticipate it will be re-marketed in Spring 2020; someone is still faffing about with their 'chemistry set' to get the adhesive sorted .... so! panic over in one respect.
On a personal note, I am using Evorel Conti as an alternative, and other than a lot of headaches, I have noticed no other significant difference in how I feel; my biggest concern was its potential to alter mood (I have developed Meno anxiety), but all is fine in that respect.
I did have other options to try, eg Oest patch + oral Prog, etc, but the convenience of a single patch (for me) was the primary reason for trying the Ev first.
