The absence of pregnancy vomiting reaction at six weeks of pregnancy may be a normal manifestation or there may be a problem of fetal arrest.
Early pregnancy reaction is a series of reactions in early pregnancy, related to the fluctuation of various hormone levels, mainly manifested as elevated body temperature, depression, drowsiness, nausea, vomiting, etc., often appear in about six weeks of pregnancy. However, a small number of pregnant women do not respond significantly to hormone fluctuations, and can have no obvious reaction throughout the pregnancy, which is a normal phenomenon.
However, if the embryo stops developing and HCG levels no longer rise rapidly, it may also cause pregnant women to have no obvious early pregnancy reaction. If you want to identify, it is recommended that you go to the hospital to have blood drawn and check the ultrasound, as long as the embryo is normal.
