Don't eat too greasy food during pregnancy. First, it can prevent morning sickness. Second, it will be difficult to prevent the baby from gaining too much weight. But many pregnant women can't eat if they are too greasy, so don't worry too much.
The second is to pay attention to exercise. Especially in the first few months, my body is not particularly heavy. If you can work, you can continue to work. If you stay at home and get pregnant, go downstairs for a walk in the park every day.
If you have practiced yoga, you can practice yoga for half an hour to an hour every day, which can not only ensure that you don't increase excess fat, but also make yourself more powerful.
Generally speaking, it is normal to gain weight during pregnancy. You don't have to deliberately keep your weight and pursue a perfect figure. Just pay attention at ordinary times and don't be too lazy.
