First scan!

Okay so I had my first scan today. The doctor said to wait 1-2 weeks as I was 5 weeks at the time she confirmed my pregnancy. Today would mark 7 weeks. The ultrasound measured 6 weeks 1 day and the internal measured 6 weeks 4 days. If it was just an empty sack, would it have passed by now? The lady who did the scan said to come back in another 2 weeks as she couldn’t see a pole or heartbeat. I never got an estimated due date either. We were hoping so much that we could see something as we were planning on surprising my partners Mum for Mother’s Day and for my dads birthday with ultrasound photos. What does it look like to you?
