So somehow nurture changed how far along I am

Melissa
My due date is August 16, 2016. 4 days ago it said I'm 5 weeks pregnant. So I'd be 5 weeks 4 days today. Well now it's saying I'm 5 weeks today. I don't understand it cause clearly I'm over the 5 week mark. I was updating my health profile but I still don't see how I accidentally changed it. My due dates the same, just how far along is wrong. Anyone know how to fix it?
