Homogenous Lining for Fully Medicated FET

I am on day 5 of taking estrogen (2mg orally 3x a day) and lupron 5 units. I went in for my first lining check and the ultrasound tech reported that my lining is already over 10mm and homogenous. Has anyone ever had this happen and it change to trilaminar later? Or should I go ahead and plan to cancel this cycle and start over? This is my first FET after having my son 17 months ago (C-section) and I never had an issue getting a trilaminar lining before now. Just feeling defeated. 😞
