So, apparently, my sister's new doctor thinks she is farther along than we had first gathered. Her first doctor said she was about 8 weeks (at her first doctor's visit in July) and her due date was going to be February 20th.

She didn't like this doctor as he made her very uncomfortable, so she made an appointment with a new doctor. She went for the first time yesterday, and he is thinking that she might be 23-24 weeks along, instead of 20 (as she is this week).

How can a doctor be so incredibly wrong about how far along she is? We're hoping the next ultrasound can either confirm or deny this claim, since that means we'd have to get busy planning a baby shower since the baby would be coming near the end of January, not the end of February.
