Due date discrepancy?????

I know logically you would go by whatever the baby measured during ultra sound and the due date the dr estimates (October 23-25th) but I am so big and just really feel like my baby is going to come sooner than expected. Not only has she measured at least 2 days ahead but My lastperiod was actually my miscarriage and if we went from that date my expected due date would be October 17th... I’m just so ready for her to be here
