Progesterone shot timing?

Alex • ✨ Due March 2021 after 4 IVFs, 2 transfers, and 1 anembryonic pregnancy ✨

Do progesterone shots have to be the same time every night, or just whenever? My paperwork doesn’t specify, and I’ll ask tomorrow, but if it needs to be the same time daily, that will affect what time I start them tonight. Thanks!
