Pregnancy calculation

Jade

Hi all!

I’m new here and have previously used the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> to help me conceive...the app was almost completely accurate with my period start dates etc (usually I was a day earlier than stated)

The glow nature app has said I am 5+1, old <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> states 5w so not really any difference.

Now this is where I struggle because clear blue told me I am 2-3 weeks?

What I would like to know is if the app is right in what it says with how far along I am?

Thanks in advance x
