Two weeks behind ☹️

Demi

Hi everyone! I just left my suppose to be 8 week ultrasound appt and I was only measuring 6 weeks 1 day and we could see a faint heartbeat but wasn’t able to measure it. Based on last period which was 6/14/20 I should be 8 weeks I had a positive ovulation tests on 6/27 and 6/28 so is there any chance I am measuring ok? Any insight would be great doc says likely misscarriage and is rechecking again on Friday.

Thanks!
