Hello everyone. Girls, tell me about the weight gain. It's 33 weeks and I already gained 27 kg ? I move a lot, 10-15 thousand steps a day, eat not much, once a day. I drink plenty of water. And the weight is growing like on yeast??? I'm worried that it's too much and will be hard to give birth and then lose it all. This is my first pregnancy. Before, I weighed 67-68, now 95???. Tell me what needs to be done with the belly after childbirth so that it goes away. Do I need to pull and all that?
