Nope... don't worry.... as the girls have said it is not accurate measuring anyway... especially if you have different measures!!! One week, I think I was about 26 weeks I was measuring 32 with the MW and she called the ob, and she measured me spot on... so really dont stress.... mind you the following appt, the same ob measured me about 4 weeks ahead and orderd a scan and bubs was perfectly on track!!!

Good Luck... not too long now!
