Due Date

Kelly
Hey all! I have a couple of apps and this is the only app that says I'm due November 12th and puts me at 4 weeks 5 days. My other apps have me due November 10 and have me at 5 weeks today. I know it's not a big difference but, I feel like in the early nail biting stages of the first trimester it is kind of a big deal. I mean each week is a big milestone or to me it is bc I just had a miscarriage. So should I go by GLOW or the other apps?
