Diamond and Bella, thank you.

Diamond - you're right about it being a small relief to know that conception and implantation can at least occur... I've been looking at some stats and I've seen in a few places they reckon 50 - 60 % of first pregnancies are chemical only (it's weird - like the body needs a 'practice run' before it gets it right)... and it doesn't increase the likelihood of having one again.

Bella - best of luck - hope that second line was a real one!
