Sooooo I need help Ladies 🤦🏾‍♀️ My First early ultrasound

Nadia • Graduate 🎓, Wife 💍, I’m An ♒️, I’m Nadii Bee 🐝 infinity and God has been blessing me on this journey called life!

I got my blood results back today and my HCG is at a 185.52 which means I am about 2-3 weeks right?

So now I look on this pregnancy glow app and it’s saying I’m 4 weeks and 1 day... counting the first day( or last. Which ever one they asked for)of my last AF...

How can I like update it and change it to the correct amount of weeks? I’m not trying to be gassed out here In these streets lmao 🤦🏾‍♀️
