If you take progesterone for progesterone supplementation and take it orally during the second half of your period, and you have spotting bleeding before you reach the number of days required by your doctor, you can continue taking it until you stop taking it after the number of days required by your doctor, and you will have your period 3-7 days after you stop taking it. If oral progesterone is clinically used to settle the fetus, and there is still vaginal bleeding while taking it, it may be clinically caused by the embryo not developing or the amount of progesterone applied is not enough, and it is recommended to decide whether the dosage of progesterone needs to be adjusted according to the specific situation. In addition, if progesterone is used to induce menstruation and spotting-like bleeding occurs after 3 days of use, it is recommended to stop using the medication and menstruation will occur 3-7 days after stopping.
