Pregnancy without vomiting does not necessarily indicate a woman’s good constitution, as follows: In the first case, it is possible that the woman does not have a significant increase in progesterone in her body and does not react with morning sickness, vomiting and other gastrointestinal discomfort. When there is no vomiting after pregnancy, if there is no lower abdominal pain, vaginal bleeding, the levels of blood HCG and progesterone are in line with the gestational week, and an ultrasound examination is done at more than 40 days of pregnancy, there is a full gestational sac growing in the uterine cavity as well as the pulsation of the primitive heart tube, it means that the early embryonic development is normal. In the second case, there is also a possibility of embryonic abortion. It is necessary to review the gynecological ultrasound and take blood test to confirm the diagnosis. Eat a light and nutritious diet, eat more meat, fish and shrimp, eggs, fresh vegetables and fruits to meet the embryo’s early needs for protein, vitamins and minerals and trace elements, keep your mood relaxed and strengthen your resistance and immunity appropriately.
