when will I bump?

Britni šŸ‘ ā€¢ due Nov 5th, 2O18 šŸ‡šŸ’Ÿ

8 weeks 1 day today, very first pregnancy so I expect to pop out a little later. I was underweight at 107 with a bmi of like 18 but I have gained 4 pounds already. Anyone got like, an estimate of when most first pregnancies really start to show? I'm ready for my baby bump! thank you
