It is very good to eat oranges in early pregnancy because they contain a lot of vitamins, especially vitamin C, which is good for the fetus as well as the mother. You need to pay attention to the amount you eat each time and avoid over-eating to prevent the possibility of abdominal discomfort or even diarrhea. The fetus is unstable in the early stages of pregnancy and it is easy to have a miscarriage or abnormal fetal development. Diarrhea may stimulate the uterus to produce contractions, which may lead to a miscarriage. In the early stages of pregnancy, you need to take folic acid on time, pay attention to avoid the possibility of neural tube abnormalities in the fetus, pay attention to nutritional intake, get more rest, avoid overwork and stay up late, have regular prenatal checkups, and actively improve pregnancy tests.
