Lining not getting thick

P • 🤰🏻with IVF baby - 2 canceled transfers - IVF Mar 21’ 3 PGT normal - IVF July 20’ no blasts - 3 IUIs - 1 pregnancy of unknown location

My lining has been hovering around 6.5-6.8 for a week and my doctor really wants to see it above 7. I’ve been on estrace (2x—>3x) for 2 weeks now. She asked us if we want to add intramuscular injections to see if that will help or scrap this cycle and start again with the injections.

I’m leaning towards adding on now since we aren’t that far away but I don’t know if anyone has been in this same situation. Would love your advice!

For reference I’ve been doing acupuncture 2x a week, wearing socks, drinking warm beverages and just started on vitamin E.
