When will the baby bump start to show?

Hi mummies. I am currently 13 weeks now and im curious when will the baby bump will start to show? My appointment is in 4 weeks from now and i will tend to overthink if my pregnancy is doing well or not as i had 2 miscarriage at 7 weeks before this. Im a bigger built with tummy fats so it makes me hard to know when my baby bump will show. Appreciate for the replies ☺️ #firsttimemom
