First time posting. I’m really confused... I just got a positive pregnancy test so I updated my status on Glow and also downloaded Glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a>. Glow says I’m 4weeks and 2days, while Glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a> says I’m 3 weeks 3 days. Which is right?

For reference, my last period started Jan 27, I ovulated Feb 15, and my average cycle length is 33 days. (Does this matter? I thought how many weeks pregnant you are is just based off your last period date, so I’m lost)

Any help is appreciated!
