Confused

So my due date is the 25th of July which by BG puts me at 17+5 but my OB said i was 18+4 with the same due date, im really confused can anyone explain?

Did s/he do an ultrasound or something? Maybe you are measuring closer to 18+4? Because you are right about the weeks.

No she didn't do an ultrasound she just used her Date wheel chart thing and it said 18+4 ad when she left the room i grabbed it and checked and sure enough it said 18+4 it was very weird i think i will just stick with my original weeks counting cause it just hurts my brain  

You go by whatever due date your doc gives. A week or two in either direction doesn't mean a whole lot.

Though I did a search and everything puts you at 17 weeks, 5 days. SO who knows
