I was showing at 12 with bloating but I didn't get my real baby bump until 18.

I started to show at around 5 months I'm 7 now but still small

I didn't till like 17 18 weeks and I'm still small for 6 months

with my first I started showing 15 weeks, but I already had a little belly it was just the part of it i couldn't suck in lol!

I started showing between 11 and 12 weeks! Not big, and not noticeable by others, but I could tell lol
