I was 26 when we started and DH was 32 - we've been trying for 22 months and counting! We've had all the tests done and there is no medical reason why we can't get pregnant - our specialists says we're just one of the unlucky ones!
Boo... i noticed some m/c's in your siggie... sorry to hear that. But wondered if you had immunology testing done? There's a thread on it - I think on the IVF board, which you might be interested to check out.
