From the discovery of pregnancy, we need to supplement nutrition, because the embryo needs a lot of nutrition once it is in bed, in order to make the embryo develop normally. It is recommended to eat one egg, one or two fish or one or two meat, one pound of rice or one pound of noodles, one pound of fruits or one pound of vegetables, and one glass of milk every day, so that the nutrition can be balanced and beneficial to the growth and development of the fetus. And it is recommended to eat more sea fish before two months of pregnancy, sea fish contains a lot of lecithin, which is very good for the development of the fetal brain. It is also recommended to take calcium supplements after the 12th week of pregnancy, because the amount of calcium needed by pregnant women will increase, and calcium from diet alone is not enough, so you need to take calcium supplements and get more sunlight.
