With my third people started to notice around 16 weeks. I'm currently 17 weeks and this was pretty much my last weeks where some of my clothes could hide it. I know the majority of my tummy is fat since I had my third one year ago .
Like the second I got pregnant lol. Basically!
About the same as you. Maybe a bit earlier, it was mostl likely bloat but it neer went down just got bigger! I was looking at y belly pics a few days ago and there isn't much difference between the 27 and 37 week pics so I guess that's when it started to slow down!
I was my biggest with her and she was my smallest baby.
