Lupron trigger for IVF (FET cycle)?

Lulu • 32 years old. Endometriosis. Surgery in January. Unsuccessful IFV in May/June. Unsuccessful FET in July. Trying again.
Has anyone else used Lupron as a trigger in your <a href="https://glowing.com/glow-fertility-program">IVF</a> cycle? I am wondering how many days after you triggered you got your period.
I had assumed I would get it around cycle day 28 as usual, but the nurse just told me I may get it sooner ("since you took Lupron.") I took the Lupron trigger nine days ago. 
(Am really eager to get my period so I can start the FET cycle before my clinic closes its operating room for annual maintenance month!)
