How long does it take for a woman to get her period depends on the cause of her menstrual disorder and the severity of her condition, so it cannot be generalized. If a woman is late in getting her period, she can visit a gynecologist or Chinese medicine department in time and be treated under the guidance of a doctor according to the specific situation. If the patient is not getting menstruation due to Qi stagnation and blood stasis, she can take Easy Pill for treatment, which may take about 2 weeks to be effective; while some patients with more serious condition may need to take 3-4 weeks to get menstruation. However, if the patient is too weak in qi and blood, or if the absence of menstruation is due to cold in the uterus, taking Easy Pill may not be effective. If a woman is late in getting her period, she should first clarify the cause of the problem, whether it is due to irregular menstruation or other reasons, and then follow the doctor’s instructions to deal with it.
