Whether or not it is normal to have brown discharge after taking progesterone for 6 days should be determined on a case-by-case basis. If it is to regulate menstruation after taking progesterone 6 days after the brown discharge may be a normal phenomenon; if it is to protect the fetus, after taking progesterone 6 days after the brown discharge, it may also be the pathological phenomenon of preterm miscarriage. 1. Normal phenomenon: As progesterone is a progesterone drug, after eating progesterone can supplement the body’s progesterone, and then stop using it, the body’s progesterone level drops, resulting in endometrial shedding, manifested as brown secretions. So if you are regulating menstruation after taking progesterone for 6 days with brown secretions suggesting that menstruation will come, this phenomenon is normal. 2. Pathological phenomenon: If it is to protect the fetus, after taking progesterone 6 days after the brown secretion suggests that the body may be low in progesterone leading to brown secretion, or progesterone levels have not reached normal values so that the brown secretion, this situation is not normal, may be the phenomenon of preeclampsia. If you have brown discharge after taking progesterone for 6 days, you need to go to the hospital to clarify the cause and get treatment under the doctor’s guidance.
