Due date bump?

Ma

So, hubby and I only had sex once the entire month of October. Not even any extra kinky play that could have risked anything. Based on my LMP, I should be 10+5 today. However, when my doctor came in for my appointment, she told me they had moved my due date to July 2nd, a full week earlier based on the size of the baby. That would make me 11+5 now, so I'm a bit confused. Anyone else have the doctor move their date that much?
