Help Please?

Tiffany • Mommy To Baby Boy Daxton 11/25/17 and Baby girl Elianna 11/25/18. Yup my babies share the same birthday 🥰 Baby #3 Raelynn 💖 due 02/23/20

I just found out I’m pregnant again and when I changed my status to pregnant glow gave me my due date and everything, but it seems as if it’s still going from my 1st pregnant because it’s saying I’m 69 weeks pregnant. Is there a way to fix this?
