Due date change??? Confused

Question

Okay guys this might be long, if so I’m sorry! 
I had my first US today and I was supposed to be 9+4 based on LMP. But the ultrasound put me at 7+6? My first pregnancy was spot on so I’m out of my element. 
But I’m confused because IF that’s a correct date from the ultrasound I must have started feeling pregnancy symptoms like.. dang.. the next day or something 😂 
My LMP started 02/08 
I already had that feeling like I KNEW I was pregnant and took a test 03/03. Negative. Kept taking them but didn’t get a positive test until 03/16. 
Im posting pictures from my OVIA app where I recorded LMP, sex, and tests. 
Any thoughts ladies? Could the baby just be measuring small right now and messing with EDD? Or am I just crazy and should follow the Ultrasound?

Answer

Being UK based I can only tell you what I've been told. We have our dating scan between 11-13 weeks. This is because prior to then, dating a pregnancy can be difficult and more inaccurate. By around the 12 week mark all babies measure about the same. 
something like that anyway so I wouldn't worry too much yet x

Answer

If there was a heartbeat and everything seemed ok then the dating matches closely with when you got a positive test.

Answer

This way maybe you can compare??& weeks are at bottom of each one😅

Answer

This was my imaging done this morning...

Answer

You might have ovulated later than what the app is guessing

Answer

I was due Aug. 20th, but was changed to the 25th, but my daughter is measuring a week or 2 ahead, but my dr insists that the first ultrasound she did is the most accurate, so she says my due date is the 25th.
