Symptoms of early pregnancy should occur after 40 days of pregnancy before pregnancy reactions appear. Nausea, vomiting, loss of appetite, anorexia, dizziness, drowsiness or body aches and weakness may occur only after the menstruation is delayed for ten days and the fertilized egg is laid. These are all normal pregnancy reactions and do not require too much stress. If you have pregnancy reactions, you should relax and divert your attention to reduce pregnancy reactions. You should also try to pay attention to a light diet, do not eat too greasy and spicy, stimulating food, otherwise it will easily increase the burden on the stomach and intestines, resulting in pregnancy reaction symptoms aggravated. If you experience severe pregnancy vomiting, you can take vitamin B6 to relieve the symptoms. This drug has an antiemetic effect and also regulates nerves and improves nerve dysfunction.
