Money, insurance and infertility?

My husband and I have not exactly been ttc for a super long time, but I am losing faith rather quickly. So, my question is for all the women who had to use a fertility clinic. How much did it cost? Did you get any help from insurance companies? Hopefully it won't come to that, but I am just trying to get a grasp on the financial aspect of it if it does. I figured I would ask some of you ladies before I started making phone calls when I really should give it at least 6 more months before I start looking up fertility clinics. Thanks in advance!
