Measuring much further along than they thought?

Hey ladies, so my due date is supposed to be July 10th, however.. I went to my doctor’s appointment this morning and they told me that I was measuring 35 weeks along, when I should only be 31 weeks and 6 days. We’re doing a sonogram at my next appointment in 2 weeks to see what the deal is.

Has this happened to anyone else? Was the baby just big or did they actually get your due date wrong somehow?

I’m kind of freaking out as this is my first baby, and I was pretty comfortable with still having 8 weeks to go, but now that’s been cut down to 5 weeks (if I actually am 35 weeks and she’s not just gigantic for being 32 weeks or something) I’m kind of nervous!
