no change for embryo development for over a week?

Ai
Is this the same for everyone's home screen? 
From 5 weeks 2 days to 6 weeks 6 days the information on the embryo's development has no change in size or weight. 
Surely this isn't accurate? 
Edit: apologies for being a bit vague (pregnant, that's my excuse!!), I meant that on the app the development changes don't show growth. Not my actual fetus. Will attach a screen shot.
