Wow you should have gotten a second opinion after the first 3 months of Clomid. I have PCOS and it is only controlled with weight loss (I am 5'8" and has to weigh between 130-140 pounds to conceive) and I wasn't diagnosed with it until March of last year after seeing an OBGYN and doing a hormone panel to find out that I hadn't ovulated in the last year. My doctor didn't even recommend Clomid because I hadn't ovulated in the last year. You should have completely skipped the Clomid until you saw a fertility specialist and had the appropriate blood work done. Seeing my fertility specialist was the best thing that ever happened to me and I was 23 years old when I first started seeing her and I am now almost 17 weeks pregnant. Good luck!
Why does a fertility specialist scare you, because it's the end of the line if he or she can't think of anything for you, or because you think the procedures sound scary? My feedback from going to one is that if you select a well-respected RE (reproductive endocrinologist, which is about as "fertility specialist" as there is), you will be well taken care of and will come away with hope.
There's nothing wrong with trying alternative remedies. Just don't do it forever, fertility is a calendar game and being 29 is better than 30, and being 30 is better than 31, and so on.
Good luck, hon. I had my first baby when I was past 50, thanks to a donor egg. A door never closes but a window opens. Take care.
