If you drink coffee in early pregnancy, pay attention to observe whether there is abdominal pain or vaginal bleeding, generally it does not matter, pay attention to regular maternity checkups at the hospital, follow the medical advice and avoid excessive tension. Because coffee contains more caffeine, so you should not drink coffee in the early stages of pregnancy. Drinking a small amount of coffee once in a while usually does not have a serious impact on the development of the fetus. Caffeine can affect the quality of sleep, lead to indigestion and cause gastrointestinal discomfort. Avoid carbonated drinks, strong tea, and alcoholic beverages during pregnancy. The first trimester is a critical period for fetal development, and pregnant mothers need to be especially careful to eat fresh vegetables and fruits and protein-rich foods, avoid overexertion, and stay in a relaxed mood.
