FET may get cancelled/delayed - what would you do?

My FET (34f) was originally scheduled for today (🥲), but after my lining check last week where it measured at 7.0 they delayed it an additional week and moved it to 12/9 tentatively to try and hit their clinic threshold of at least 8.0.

My fully medicated cycle protocol has been 3x weeks of BC, followed by estrogen patches switched every other day with an increased number of patches over time (currently doing 4x), AND they added an additional estrogen suppository this past week only to see if it would help.

My check this AM was 7.2... My lining is a trilinear pattern still which is good, but I’m pretty nervous they are going to call me soon and try to cancel it. Not sure if there’s any connection to this, but I went back to my prior ultrasounds and my lining right before retrievals was a 6.8 & 7.1 so I feel like this is just where I’m at in terms of what my body is able to do??

In my position, I’d love to know if you would try to advocate for it to move forward next week as planned still or let them cancel and try a different protocol in the future? Any advice would be appreciated as I wait for their call to come in!!
