When choosing to use progesterone for disease treatment, the time required needs to be judged according to the patient’s specific condition. If the patient wants to delay her menstruation, she can take it before her period for about 3-5 days, and the onset of menstruation can occur about 3-5 days after stopping the medication. In the case of early pregnancy, the condition of pre-eclampsia occurs, especially when the progesterone test in the body is significantly lower, while using progesterone drug treatment, it is necessary to choose the time to take it according to the patient’s specific condition and the blood progesterone test. When the patient’s condition is obviously relieved and the blood progesterone test is stable, it means that the ideal treatment effect has been achieved and the use of drugs can be stopped.
