Hi guys! So I am very confused! I just had my first ultrasound. Based on my last missed period I was 10 weeks, however the ultrasound tech said I was 10 weeks and 4 days, then I go see my obgyn and she tells me I am only 7 weeks that that's what the tech put down. So I'm confused I don't know what to go off of. My ultrasound picture says 10 weeks 4 days!
