Scooby, I realised I had no idea what normal progesterone levels in pregnancy are... and google has just informed me that yours are MASSIVE! Are you still using pessaries/crinone? You've got extremely good HCG levels too, so chances are this pregnancy is going fine. And now I WISH my clinic had let me know what my numbers were! They do say that high progesterone levels could indicate twins (how many embryos did you have transferred?), but with being an IVF pregnancy, chances are it's just from the luteal phase support they give you.
