That's awful that you're waiting to be seen at the clinic, but doesn't surprise me, unfortunately.
I've just had some unexpected progress actually - not a conversation with a GP, but a GP has asked their surgery pharmacist to call me and offered some new treatment options. In order of recommendation:
1) oestrogen patch + Mirena coil (so the progesterone is not systemic, which I seem to be struggling with)
2) Femoston oral tablets
3) Timbolone (not HRT, synthetic)
4) oestrogen patch and progesterone pessary (sounds gross, but principle is same as #1, I guess)
The GP's pharmacist was very helpful on the phone, but said I should look on this website to help me make an informed decision, and tell them what I decide through the surgery group's online form, so I'll do that.
Wonder if anyone here has any positive experiences of the above combos for peri?
