Question

So I had my ultrasound Friday and I am given so many different information. I assumed my period was May 4. I am pretty regular. My last real period was April 10th with a 24/25 day cycle.

May 30, I had blood work done and it was in the 5 weeks range 497 hcg) so if I counted 5 weeks back it puts me before I started bleeding.

I had an ultrasound done on Friday and they measured 8 weeks and 3 days.

Then I pulled up the results online and it said 7 weeks.

And according to THEIR ultrasound measurements, they put the due date of February 8 and that is past 40 weeks.

I am confused. Please help me out. Should I get a different opinion?
