Anyone ever do an HCG booster trigger shot?

I had my 7dpo Progesterone test today... I guess it came back on the lower side, because my dr wants me to do the trigger booster (Ovidrel) again tonight. Anyone ever do this?

Re: Anyone ever do an HCG booster trigger shot?

During my IVF cycle, I triggered on a Friday night and went into the office for bloodwork on Saturday to make sure that my levels were high enough. They weren't. So they prescribed me another hCG and had me trigger again that night.

My RE said that when they went to do the ER on Sunday, if they weren't getting eggs out of my follies that they would let me go home and try again the next day, after the second shot was fully in effect. That didn't happen and my ER went fine.
