A body temperature of 36.6 at nine weeks of pregnancy is normal. Adults generally measure their body temperature by measuring the temperature of the armpits, and a normal body temperature fluctuates between about 36℃-37℃. The average body temperature of women is slightly higher than that of men. A woman’s body temperature may be mildly elevated during the premenstrual period and early pregnancy, and lower during ovulation. After pregnancy, due to the effect of progesterone, the body temperature will be 0.3-0.5 degrees higher than the previous basal body temperature. Therefore, a body temperature of 36.6 at nine weeks of pregnancy is normal. If you have an elevated body temperature during pregnancy, you need to pay attention to any other comorbid symptoms, such as coughing and coughing up phlegm, abdominal pain, etc., and actively seek medical attention to exclude the possibility of related systemic infections. As long as the temperature during pregnancy is within the normal range, there is no need to worry. During pregnancy, you need to have regular checkups, pay attention to warmth, avoid catching cold, and consult a doctor if you have any discomfort such as abdominal pain or vaginal bleeding.
