It is generally normal for the body to have no reaction to pregnancy 9 days after ovulation. Usually, early pregnancy reaction will appear in 6~7 weeks after a woman’s pregnancy, and the pregnancy may be detected by drawing blood to check the level of human chorionic gonadotropin in the blood, but at this time, women usually do not have nausea, vomiting, drowsiness, fatigue and other early pregnancy reactions. In the early stage of pregnancy, the cell division of the embryo is relatively fast and the development of the embryo is unstable, so women should pay attention to rest in the early stage of pregnancy and avoid overwork and strenuous exercise. If a woman is pregnant 9 days after ovulation and has nausea and vomiting symptoms, it may be caused by other reasons, and it is recommended to go to the hospital in time for targeted treatment.
