Is there such a thing as a progesterone implant? I'm still struggling with getting my HRT 'tuned' and can't get the patches to stick, but really want to take the oestrogen transdermally so the Dr has suggested having the Mirena coil refitted for the progesterone (had it removed as was told I didn't need it anymore cause had gone through the menopause!)but I can't stand the thought of the pain - I haven't had any children and when they opened my cervix I felt like I was going to die - so if there is an option of having an implant instead I'd much prefer it?
