All women are different. They see your baby in ultrasound and hear the heartbeat, right? I'd take yourself as lucky. With my first pregnancy, I wanted to bump into maternity clothes the worst way. I had some cute ones waiting and wanted to look pregnant. But with my first pregnancy, my muscles really held me in. I finally very low and I mean VERY low felt a bit of firmness. The all of a sudden, it all busted free about 23 weeks for me. Then I went from not looking pregnant at all and having to search from signs to people asking me when I was going to deliver. Bam. That fast. So, soon enough, you will bust free and have the pregnant belly, no worries.
