When does weight gain begin during pregnancy?

Oh, weight gain during pregnancy? It starts the minute you see that second line on the stick, haha! Seriously though, it's usually very gradual in the first trimester, maybe 1-2 kg, then picks up properly in the second and third. Your body is doing a lot of work, so don't stress over every gram.

Weight gain starts officially when your body realizes it's making a whole human, so pretty early! Even if you have morning sickness, some women still gain a little in the first trimester. Then, by the second, it's like 'Hello, baby bump and snack cravings!'

Yaar, actually, for most women, weight gain starts slowly in the first trimester itself, though it's not much. Then in the second and third trimesters, that's when you really see the bump growing and the numbers on the scale going up. It's all part of the process, don't worry too much!

It can begin very gradually in the first trimester.

My sister told me she started gaining weight pretty early, even in the first trimester, just a little bit. Then it really picked up in the second. So yeah, don't expect to stay super thin, it starts almost right away for most people.
