Confused by how far along I am

I called and made my first Dr. appt and she said they schedule at 6 weeks so she scheduled it for September 10th.  My last period started on July 28th and I tested positive on August 25th.  I thought I was 5 weeks now (Sept 3) and that matches with what the Dr said.  The bump tells me I'm 5 weeks but then today I got an email from The bump's partner EveryDay Family and that says I'm 6 weeks but they both have the same due date???
