I've just had my second FET cancelled due to my lining not thickening - was on progynova 4x a day from day one. It went from a 6.8mm to a 6.3mm (plus the trilameter looked not as obvious so it was obviously breaking down). Am sooooo frustrated. The first one was cancelled because my lining wasn't great either, though I did have covid a few weeks before which caused a mid cycle bleed which I think ruined it (though now i'm starting to think it would have been crap even without the random bleed).
Anyways am feeling a little hopeless and sorry for myself right now. Waiting for the doc to call me today/tomorrow about a new plan as clearly progynova 4x a day isn't working for me. The nurse said they might want to introduce patches with the pills if not maybe try some form of natural cycle.
What has other people's experiences been with lining issues? What if anything ended up working for them? This process is so deflating, and what stresses me out the most is that we're not even getting to the hard bit (i.e getting the embryo put in and no miscarriage/ectopic like i've had before)
