running out of options

I did ovarian drilling in January didn't get any positive or. my husband and I decided to go to a fertility clinic did Clomid 50,100&150. we haven't been successful and I'm losing all hope. can't even do an <a href="">IUI</a> on my island or get a trigger shot because it's not available anywhere on island. we've spent over 30,000 $ in fertility treatments. each time I get a little more depressed than the previous time. fertility specialist is advising to do another round of 150 Clomid I'm lost at this point.
