My last two OB appts my belly has measured two weeks ahead. When I was 23 weeks it measured 25cm(weeks), and then yesterday at 27+4 weeks measured at 30cm(weeks). She said its normal range and isn't concerned. My original due date was Oct 25th based off my lmp, and first ultrasound. Two weeks after they said the 25th they did another ultrasound and changed it to the 31st. I know it's only an estimate but since my belly is measuring larger do you think I'm further along than what my due date is (the 31st)?
