Fertility treatments?

I have poly cystic ovarian syndrome. So it is diffict for me to get pregnant and I need help from a doctor. Today I am going in for my ultrasound and they can tell me if I am ready or not to start my injectables. They have me taking bravelle and ovidrel. Has anyone had to take this? Has it worked? It is so expensive. I hope this goes quick. I'm so nervous about all of this but I think I'm just ready for all of this to happen already.
