I’m 9 weeks and my other <a href="https://play.google.com/store/apps/details?id=com.glow.android.baby">baby app</a> said I should feel my belly getting hard. My belly feels the same. It’s getting rounder at the bottom but not hard. I’m 5’5 and I’m 218lbs. Should I be worried that my belly isn’t hard like the app says? Also being plus size, would I be able to pick up the baby’s heart beat on a Doppler at 9 weeks? I ordered one online. I’ll be 10 weeks by the time it arrives. TIA
