Progesterone symptoms of fever?

Virginia • Mom to 5 through adoption and foster. 11 yrs TTC without intervention, unexplained infertility. 2 rounds IVF, FET #1 due 7/9/20💙

So a crazy thought that is probably wrong. Has anyone or is there any scientific reason why I might feel yucky and have a low grade fever after taking PIO? It started yesterday afternoon (first shot in morning) and was gone before bedtime. Started again this afternoon after taking another one this morning.

I know it's possible I'm just sick, but I'm concerned because I'm supposed to have my FET Tuesday. Thanks!
