Thanks Rach and Georgi

Rach - I am from good old Perth, Western Australia. The Ob told me that the range for 3-5 weeks is 50 to 5000 (which is very different to the information that I have found and from what Jas posted on this thread!) and then said that for 4weeks 3days 720 is too low based on that range.

I guess I just have to wait and see what Monday brings.

Thanks again
