Low mood in your luteal phase

Low mood is feeling flat, tearful, or down without an obvious trigger. In your luteal phase it tends to flare because the pre-period drop in estrogen and progesterone lowers serotonin activity, which can flatten mood.

What's happening in your luteal phase

Progesterone rises then falls. Energy tapers, cravings and bloating can appear, and slower strength work plus magnesium-rich food help.
