Sorry, I hate that I have to be anonymous but my husband and I don't want to tell anyone yet. I feel like if I stay anonymous I can at least as questions and nobody will ever know it's me lol. Anyway my last period was from December 17 to December 20. I found out I'm pregnant. How many weeks am I? I don't seem to understand how that works. I assumed I am like around 2 weeks but when I calculate in glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> it says 3 weeks 5 days.. Idk how that's possible. UPDATE: Thank you everyone that makes sense!
