Strawberry - You may find that your GP will be hesitant to refer you to a specialist before the 12mth mark. Just so you can be prepared. Clomid is really beneficial if you ovulate late as its an ovulation induction treatment. I ovulate fine so it was of no benefit to me other than over stimulating egg production. There are heaps of reasons as to why it hasn't happened yet...
Charting is good, worth taking them to the GP when you go in case they help your case.

FWIW - I have tried all of those things too, and didn't find a miracle answer. Although the AP certainly worked on perfecting my cycles which was nice. And was really good for calming me down.
