Do you always show sooner/bigger with your second?

I’m pregnant with #2 and definitely feeling nauseous and exhausted already and I know it’s early on but I seriously feel awful and i never did with my first. But I’m short and already on the chubby side so I’m worried I won’t be able to hide this from family/friends very long.

Do you always show sooner?

Do you always get bigger with the second pregnancy?

Is there anyway to lose a little weight or gain minimally to have a healthy pregnancy and baby without becoming more overweight? I’m at a higher weight/BMI than is ideal for my height and I don’t want to gain too much to put the baby at risk.
