Hello, today I am about 8 weeks and 1 day pregnant. I had my first ultrasound on Jan. 24, 2014. My last period was on dec. 3, 2013. My ultrasound said that the baby was measuring about 7 wks and my due date is sept.12,2014. I ve also asked about the concieved date, and the nurse had said that the conceived date is estimated about dec. 20, 2013. So, is 7 weeks measured from the conceived date or the last first day of my period?
