Calendar and daily update don’t sync

Nichole

I am due August 9th. My daily update says I am 11 weeks 5 days today. But when I click the baby image to see size or look at the calendar of weeks, it says today is 12 weeks even. Am I looking at something wrong? Other app also says 11 weeks 5 days but website calculator says 12 weeks. 🤷🏻‍♀️
