Thank you sooo much everyone - just back from the doc now - scan wasn't any help, so I have to go back for another one in 10 days. My second HCG level is 60551.... so it isn't a lab screw up, but it also isn't doubling very quickly (it is a 5.5 day doubling rate).

The doctor thinks that I may have ovulated twice in Nov - one could have been a blighted ovum which explains the rise in HCG then fall over 24-29 Nov- and a second egg could have been fertilised on the 25 Nov........ I don't know how likely this scenario is - but I like the idea!!!

Anyway there is nothing I can do except try to forget it all until the next ultrasound and hope that lets us know something. If I am six weeks pregnant a 5.5 day doubling rate seems a little slow????

Thanks again everyone!!!!!
