It is possible that a cold can affect the progesterone value of a pregnant woman. This is due to the fact that all metabolic functions of the body may be affected when the patient has a cold, and it may also affect the endocrine disorder of the pregnant woman, causing changes in the progesterone level in the body, but the cold itself does not have a great impact on the progesterone value, and women who have a cold during pregnancy must be careful not to use medication on their own to avoid unnecessary harm. If you are uncomfortable, you should consult a doctor in time and if you have a low progesterone level, you should adjust it under the guidance of your doctor. If a pregnant woman has a low progesterone value, she can take oral progesterone tablets or inject progesterone injections under the guidance of a doctor to replenish her progesterone until the normal value range prevails, and patients with low progesterone values during pregnancy should pay attention to reasonable rest and reasonable diet.
