Due date issues

yaya mustan
I'm so mad today. I had an ultrasound some days ago and on top of the page I was able to see 6 wk 6 days written. The rules of that clinic did not allow them to tell me anything. So I waited and emailed my doctor today who said that the clinic confirmed it was a little too early to confirm due date and they would like me to come back for another ultrasound. If I am correct then I should be 8 weeks and 3 days today but it seems like I am 7 weeks or so. My doc will soon be sending another requisition for ultrasound. But I so want to know my due date. I am so annoyed. Anyone else had this issue??
