It’s varies. Some pregnant mums didn’t put on much weight throughout their pregnancy. As long as you and your baby is healthy, don’t worry about gaining too little or too much weight
It’s totally depends on each n everyone appetite .. bt we no need to eat for 2.. can eat how much u needed that it .. weight growth we can see after 5th month mostly
Everyone is different. I gain weight after 5 months.
My appetite improved from week 18
