Introduction
In general, it is normal not to experience morning sickness by 42 days of pregnancy, as this largely depends on the individual pregnant woman's physical condition and characteristics of her pregnancy. It is important to maintain a regular作息 (daily routine), avoid staying up late and overexertion. Eat a balanced and nutritious diet, including plenty of fresh fruits and vegetables and high-quality protein, while avoiding raw, cold, and spicy foods. Maintain a positive mood and avoid anxiety and stress.

Generally speaking, whether it is normal to not experience morning sickness by 42 days of pregnancy mainly depends on the individual physical condition and characteristics of the pregnancy. A detailed analysis is as follows:

If no morning sickness occurs at 42 days of pregnancy, but ultrasound during prenatal checkups shows normal embryonic development, blood HCG and progesterone levels are within the normal range, and the pregnant woman herself has no discomfort such as abdominal pain or vaginal bleeding, this situation is considered normal. Morning sickness varies significantly among individuals; some pregnant women may not experience noticeable nausea throughout their entire pregnancy due to differences in constitution. As long as all examination indicators remain stable, there is no need for excessive concern.

However, if in addition to the absence of morning sickness, symptoms such as lower abdominal heaviness or irregular vaginal bleeding occur, or slow rise in blood HCG levels, low progesterone, and lack of visible fetal heartbeat or embryo on ultrasound are detected during prenatal exams, caution is warranted. These may indicate potential problems such as poor embryonic development or ectopic pregnancy, and further evaluation should be conducted promptly to clarify the health status.

In daily life, maintain a regular routine and avoid staying up late or overexertion. Eat a balanced and nutritious diet rich in fresh fruits, vegetables, and high-quality protein, while avoiding raw, cold, or spicy foods. Maintain a positive mood and avoid anxiety or stress. Pay attention to staying warm and avoid strenuous physical activity. Follow medical advice for regular prenatal checkups, and seek prompt medical consultation whenever any abnormalities arise.
