need someone to talk to

Hello, I am 29 years old with unexplained secondary infertility. I have a 5 year old daughter and my husband is 35. Every test we have done come out perfect. I have had two miscarriages one before my daughter and one after. I have been trying to conceive for 3 years since my last miscarriage. I have done clomid cycles. clomid and ovidril cycles as well as femara timed intercourse cycles and one round of femara with IUI. I am getting discouraged I know I can never afford ivf! Anyone have any suggestions or a similar story that got pregnant? what worked for you? Thank-you so much for your time
