I didn't start showing at six months
Every woman's pregnancy is different. I'm 22 weeks also and I don't show much. If your doctor says everything is fine, everything is fine. Baby is still growing and you'll show lol. By 7 months...
I didn't get my lil bump till 26 weeks
You could get it soon or you might not show until around 35-40 weeks that's what my friend did and she went from being flat belly to big baby bump over night
Sometimes it happens practically overnight. You'll look normal when you go to bed and ready to deliver when you wake up.
