It is also normal to not have any reaction when you are pregnant. Congratulations, if you do not have any reaction you can eat more, the child will be able to get sufficient nutrition, which is normal. After pregnancy, because of higher hormone levels, stimulation of the gastrointestinal tract leads to spasm of the smooth muscle of the gastrointestinal tract. Many people have different degrees of gastrointestinal reactions, some people vomit to the sky, some people have dry vomiting, but can not vomit up, the symptoms are mild or severe. But if you have no reaction at all, it should be a good sign, you should eat more, and then pay attention to the electrolyte balance in your body, and eat as much as you can, so that the child will develop very well in the womb. If you have severe pregnancy vomiting and can’t eat anymore, your mood will become very bad, and sometimes you have to go to the hospital to find a professional doctor to prescribe you some anti-emetic drugs, such as taking vitamin B6, and if it is particularly strong and affects the electrolyte balance, you will also have to undergo infusion therapy.
