Oh Bazz I'm so sorry! I really felt sure that this was it for you. Well done for having the courage to test, and sounds like u have a good doctor who is saying and doing all the right things for you.
It WILL happen for you, it HAS to, this thread is only for lucky people!
Keep us posted over next few days xxx
Re: cycle length. Mine wa always fairly short (24 days) but after m/c took about 7 weeks for next AF, and after that my cycle was always longer, 28 days. I know that's not long by any means, but my dates were like clockwork both before and after m/c, it was just that the length of cycle changed and didn't go back to normal. Strange!
