Apps giving me different dates?

Kristen

Okay so it’s really annoying me. Does anyone else have a few different <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy apps</a> and they are giving you different dates? They’ve all got the same due date out into them, but glows saying I’m 5 weeks and flo is saying I’m 6+1.

I’m guessing I won’t know which ones right until I have my dating scan? 🤔🤷‍♀️
