So.  I know my OB will base my EDD off my LMP.  However.  I have stupid long cycles.  I'm not the every 28 days girls.  I have on average a cycle length of 42 days.  So my LMP was Feb 5th- making me almost 7 weeks.  But I didn't ovulate until march 5th.  A freaking month later.  And I know for sure because I track and use opks.  So according to ovulation date I'm only 5 weeks.  I just hate not knowing where I'm measuring and the possibility that I am more than likely going to be measuring behind at my first OB visit.  Anyone else in the same boat???...
