twins/PIO shots question?

[carisa]

For those of you having twins, how long are you on PIO shots for? My gestational carrier is now 11wks 5days pregnant and took her last shot lastnight. She went in for an ultrasound today with the perinatologist and he said her two placentas looked great and there was no need to continue shots. So she is officially done now. I'm so happy for her, yet a little nervous for her to stop. Her progesterone numbers at 10 weeks were 31.9 and that was while on the shots. I guess it doesn't matter as much now that the placenta has taken over. Anyway, just curious when you stopped your shots? Thanks
