Thick lining at baseline scan

Hi,
I am just starting my FET an am cycle day 3 today, I went in for my baseline scan and my lining is 8mm so too thick to start meds. I’m going back tomorrow for another scan to see if it’s any better and can start but if not this cycle will be cancelled.

For a background I had a successful fresh transfer in 2022 with no problems. In 2024 I went for a FET lining was good at baseline but got thick too fast so cycle was cancelled. I had hyseroscopy with D&C to remove polyps and the biopsy showed hyperplasia. I had the mirena for 1 year and 2 more biopsies both negative and my mirena was removed in October 2025.
This cycle will be a super ovulation FET to avoid the extra eostrogen with the history of hyperplasia.

Has anyone else had a thick lining at baseline and it’s then gone on to reduce the following day?
Or anyone in a similar situation with any advice please as I’m feeling very deflated.
Thanks ❤️

Yes I have had this on two occasions and the cycle has gone ahead, just a couple of days delayed.
