Changing settings?

Katie
So I had a dr appointment today (April 6) and had my first ultrasound. The ultrasound pictures say I am 10 weeks 5days. According to <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> I am only 10 weeks. Is there a way I can change that so I'm not off by a few days? My due date is November 2
