For women with regular menstrual cycles, early pregnancy reactions can usually appear when the menstruation stops for 40 days. Early pregnancy reactions mainly include nausea, vomiting, drowsiness, frequent and urgent urination, general weakness, breast pain, etc. As long as these conditions do not affect daily life and study, no special treatment is usually necessary and you can rest in bed. If you have severe vomiting, you need to go to the hospital to keep the fetus and apply nutritional drugs intravenously to avoid dehydration and electrolyte disorders. If the early pregnancy reaction disappears before 12 weeks, you should consider the possibility of embryonic abortion and go to the hospital for an ultrasound to see if there is still a fetal heartbeat to rule out the possibility of fetal death in the womb. You can eat less and more meals and pay attention to strengthening nutrition.
