due date confusion

I am so pissed. This is like the worst day of my life !! All my pregnancy my due date was January 27 and today I met a new doctor at the clinic who said as per all the reports that she reviewed my due date should have been February 02. This close to the end and I want to cry !! How come the other 6 doctors didn't notice that. Were they all blind??? I know this new doctor is not right. I feel this baby coming soon. She didn't even ordered an ultrasound. She just GUESSED it based on my anatomy ultrasound.  So what should I do now ?? Think I'm due on January 27 or February 02??? Both my previous pregnancies my due dates were correct and I gave birth a day after due date. I'm literally crying with tears because I am so upset.
