Anxious for first ultrasound and slightly annoyed

Bea • girl 11/7/13 boy 5/27/16 #3 due 1/29/19
My LMP was 8/17 so based on that my EDD would be May 24. I didn't ovulate though until Sept 6, so that would make my EDD May 29. When I scheduled my appt the girl asked me when my LMP was, I told her 8/17 and she tells me my EDD is June 8 (this annoyed me). My ultrasound isn't until Oct 23, I should be 8w5d based on my ovulation date. I am getting more and more impatient waiting for my ultrasound, it seems so far away. I thought keeping busy would take my mind off of how far away it is but I have no symptoms and it is making me nervous and I just want to know if everything is going well. I was so sick with my first, this just doesn't seem normal to have no symptoms. I did get a little nauseous last night after I took my prenatal, that made me feel a little better, but it only lasted a few minutes.
