Ultrasound Discrepancies

Jwoww
I just found out my doctor is doing my c section early because he thinks I will be 88 weeks and 1 day on 10/23 but I will actually be 37 weeks and 2 days. but he want listen to me. Noone will he's like all of your ultrasounds put you 6 days ahead and I am like every last one of them are freaking wrong I know when u had my period when I had sex and it does not add up to their damn date I'm so mad but oh well I want to have him early i.just want the doc to understand that I will be 37 weeks not 38.
