Bloat?

Kristin • 27 married army 2 girls ( 3 & 8 ) expecting our 3rd and final princess. recent miscarriage (04/24) we found out our rainbow is due 02/13/18 :)
So I'm supposed to be almost five weeks and I've been getting some rough bloating and gas bubbles but my Nona thinks I could be further along because my bloat feels off to her lol what y'all think
