Glow vs glow nurture?

So I’m 17 weeks today; glow, baby center, and Ovia all still say 17 weeks. (I used ovia and glow to help track my period to get pregnant, and the all provide a lot of helpful info so I never deleted them🤷🏼‍♀️)

Glow nurture has the same due date and everything, and it’s saying I’m 2 days behind.

Has anyone else experienced this? I mean I’m just ignoring it but it’s kinda annoying lol
