When did people start showing?? 👶🏻❤️

Helen • Pregnant after 8 months of trying! Engaged to the most incredible man! Live, laugh, love!!! ❤️
I'm 15 weeks pregnant with my first baby, my anxiety is very high as it is and to make Things worse I'm not showing and I feel like this would really help relax me if I could just see the pregnancy developing. I'm a bit on the heavier side and do have quite a chubby tummy, could this be why I'm not showing yet?
