@Tahli I am on Oripro, and when my progesterone was very low, I was on Crinone as well as Oripro. I'm sure they are just another form of progesterone.
Both the crinone & Oripro are only covered on PBS of its a fresh transfer, and only until pregnancy is confirmed. Not covered by PBS for frozen transfer. Pretty sure this is correct.
And as for the patches, I stayed on them until around 12/14 weeks pregnant.
