Cause I feel like I'm WAY further along than they told me. I feel flutters, eat everything in sight, and it's because I'm actually hungry not just craving. And I pee with a full bladder almost every 30mins. I'm supposedly 13w.
The early ultrasounds are very accurate at determining how far along you are.. so I doubt they are wrong.. at most they may be off by a week and that can go either way. The fluttering is gas BC you would not feel the baby that early and I also had to use the bathroom like crazy around then and I wasn't hungry BC of nausea but in many woman are hungry in their first trimester.
