Well everyone's different but I'm small and petite and I showed a bump pretty fast since I'm all belly
I'm Small & Very Slim Too & I Didn't Show Until I Was 4 Months Or So
I'm tall nd was skinny ...I didn't show til I was 5 1/2 months pregnant
im 18 weeks and im barley showing
I'm tall and skinny started showing last week towards the end of 12 weeks
I'm 5'6 and 115pounds I'm 12weeks and I'm not showing it just looks like I've put on a few pounds. I can't wait till I get a baby bump though.
