Vomiting in pregnancy, in the vast majority of cases, gradually begins to lessen around the third month of pregnancy. This is because the HCG level in the body peaks at around eight weeks of pregnancy, which is around the second trimester. Then at around ten weeks the growth rate starts to not increase as much as it used to, so the pregnancy vomiting slowly and gradually decreases. During pregnancy vomiting, it is advisable to eat as much as you can to avoid the gastric mucous membrane friction caused by fasting, which will lead to more serious nausea. If the vomiting is more serious and you can’t eat, it’s best to go to the hospital for rehydration. Because the inability to eat may also cause electrolyte disorders, so it is also necessary to correct the electrolyte disorders, which is conducive to the growth and development of the embryo.
