IVF - Lining too thick

Hi All,

So we did our first round of egg collection last month and only one embryo made it to day 5- they froze it as they said my lining was too thick for transfer. This has been mentioned a few times and I had a hysteroscopy & laparoscopy last yr, its not endometriosis - i have a few fibroids but Dr didnt think they were a problem.

Has anyone else had a thickened lining? And how was it fixed? Or do they just do the FET at an earlier time in my cycle! Consultation with my Dr next week but I am so frustrated waiting on these answers!
