Progesterone levels in the luteal phase before menstruation
Disease description:
I'm currently trying to conceive, so I'm very concerned about my progesterone levels during the luteal phase. Recently, I've noticed changes in my progesterone levels and have gone to the hospital for testing. My period is also approaching, but I'm not sure exactly when it will arrive. So, what level of progesterone during the luteal phase indicates that menstruation is about to start?

Menstruation may occur 1 to 2 weeks after progesterone administration during the luteal phase. Progesterone is a hormone secreted by the ovaries that acts on the endometrium, causing the proliferated endometrial tissue to become congested and shed, resulting in menstruation. Generally, menstrual bleeding occurs 3 to 7 days after taking oral progesterone capsules. Some patients may experience menstrual-like bleeding during the course of treatment. However, if menstruation does not occur more than two weeks after stopping the medication, or if irregular bleeding persists afterward, it is necessary to seek evaluation at a正规 hospital. Assessments including endocrine hormone testing and gynecological ultrasound should be performed to evaluate the condition of the endometrium.
