Dont know lmp... first ultrasound was given to me 10/22/13 it read 8w5days and due date was 06/02/14 now due date is 05/30/14 which is correct?

Similar: First, only 5% of women deliver on their given due date. Secondly, those 2 dates are so close, it's impossible to say that one is more accurate than another. I usually say that the earlier ultrasounds are more accurate than the later ones. But it depends upon the sonographer and the resolution of the machine. Generally first trimester scans are +/- 7 days. And 2nd tri scans are +/- 14 days.
