Last week, we covered the follicular phase of the menstrual cycle, so now, let’s learn about the luteal phase!

The luteal phase begins after ovulation when the empty follicle transforms into the corpus luteum, a gland that produces progesterone. This hormone plays a key role in preparing your body for a possible pregnancy!

During the luteal phase…

👉 Progesterone causes the cervix to stop secreting fertile mucus, replacing it with a thick, sticky mucus that protects your body from s***m and microorganisms.

👉 The lining of the uterus, or endometrium, thickens to support implantation if pregnancy occurs.

👉 If no fertilization happens, the progesterone level drops, and the lining is shed during menstruation.

A healthy luteal phase typically lasts between 9 to 18 days, with an average of 12 days. It’s a great indicator that ovulation has occurred and that your hormones are in balance!

Curious about your luteal phase and what it means for your fertility? Charting your cycle through fertility awareness-based methods (FABMs) can give you deeper insights into your body’s natural rhythms. Learn more through the link in our bio!
