20 weeks and no bump :-(

Alicia • Got married Nov. 8th, found out I was pregnant 12/9... It`s been a crazy and awesome month
I'm 20 weeks 5 days pregnant and still do not have a baby bump :-(. When I lay down at night I can somewhat tell bc my lower ad is somewhat hard, but when I wake up the next morning it's squishy again :-(. I just really want a baby bump. I weigh 260 so I know it might not be as defined as smaller womens. Thankfully I have a fetal Doppler where I can hear my baby or else I would be worried she wasn't even in there.
