Fertility shots

Hope
We have been trying for about 1 and 1/2 for a baby with no luck. I have been tested each month and my progesterone levels continued to decline until I semester to no longer ovulate. I took 6 round of clomid now I'm headed to an infertility specialist. I don't really know what to expect. Does anyone have an idea of how much the meds ( shots and otherwise) may run? I'm at a dead end here and when it comes to this it's very overwhelming. Any help would be appreciated. Thanks
