my 18-20w ultrasound is booked in for the 23rd Jan... this was when my EDD was 18/6/09, but has since changed to 2/7/09 so when it comes around, ill only be 17 weeks, rather than 19. they are completely booked up, and there is no way to change my appointment.

im not sure what to think, will this be ok? will they be able to do/check everything as if i were a few extra weeks along?? im worried, but att he same time, im not sure if i should be worried??

i need some feedback!!!
