No, the 17th was 8 days before my next period was due - I was due 25 September but missed it.
But anyway, you're right. There's virtually zero chance of getting pregnant like that. I don't have a clue when I ovulate, only that it's supposed to be middle of the cycle.
My dreams were right, it certainly was 'fairytale conception' as I still can't figure out how it happened
I phoned NHS Direct to talk to a dr but they said they'd call back in 3 hours and that was nearly 4 hours ago.
I think I will wait 1 week and re-test and if it is stronger positive I will re-scan. If then there is no hope I will take the pills.
