What counts as 'popping'?

Jilly • I first joined glow to track my periods and ovulation, now I'm here tracking the progress of my first pregnancy. Jan17
How big did your belly have to get before you feel like it popped? Was it when you suddenly became noticeably pregnant?
I have a definite bump first thing in the morning (which doubles in size during the day) but it's still quite small. I look 6 months pregnant in the evening, and could pass it as just a regular belly in the morning.
