First IVF cycle

Hello ladies. Doing my first <a href="">IVF</a> cycle and Thursday is my egg retrival day. I was hoping to do a fresh embryo transfer but nurse called and said my progesterone is too high. So will have to do a freeze all and wait for my next cycle to do ET. Don't know if that's good or bad. Was reading that may be good to let your uterus get back to normal after fertility meds. Anyone have successful pregnancy after frozen transfer?
