Normally, after pregnancy, most women experience nausea and vomiting. Due to the influence of hormonal secretion in the body, drowsiness can occur, and there is weakness and anorexia. However, these symptoms vary from person to person, and there are very few people who do not experience these symptoms. As long as the ultrasound examination is done and the fetus develops normally, there is no need to be too nervous. If the early pregnancy reaction stops suddenly during the period of early pregnancy reaction, it is possible that the fetus is aborted. It is possible that the fetus has signs of miscarriage or that the fetus has stopped developing in the uterus. If there is no problem with the ultrasound examination, it means that the fetus is developing normally and no special treatment is needed.
