There is a normal body mass index during pregnancy, and pregnant mothers will have corresponding reference at all stages of pregnancy. As long as it does not exceed this range, the weight of mothers is normal, and pregnant mothers can compare it as a reference. According to the research, it is scientific and reasonable to gain weight 1 1~ 15 kg during the whole pregnancy. Then according to your pregnancy for more than 5 months, it is the second trimester, about 20 weeks. It is normal to gain weight to about 2kg. Your weight gain is within the normal range, so you need to supplement nutrition.
Someone said, is it because I eat less or supplement less nutrition? Actually, it's not. I belong to a constitution that can't eat fat. When I was pregnant with Dabao, I thanked meat and bone soup, ribs, pig's trotters and beef every day. I'm not saying that eating beef is good for children, so I often eat it. In the third trimester, almost 30 weeks later, the fetus will grow faster than in the first and second trimesters. Pregnant mothers must control their weight, but so must their nutrition.
For eight or nine months, I have felt changes in my stomach every day. One reason is that the baby grew up in the second trimester, and his stomach was also big. Another reason is that the baby needs more nutrition, and what the mother eats is transformed into the baby's nutrition.
