Twinkie, sorry AF arrived but on to the next cycle!
Confuzion - glad to see you feeling so much more positive! You're right, you've loads of time, but hopefully you won't have to wait loads of time! Also, your theory on the hCG sounds very likely - after my natural M/C at 5 weeks, I tested postive with a good, solid, mid-colour line, no squinter by any means, for at least 6 weeks. And I did ovulate, I know because I had day 3 progesterone bloods taken. So, sorry you got your hopes up, but FX for next time!
