Understanding Your Menstrual Cycle

Phases of the Menstrual Cycle

Menstrual Phase (Days 1-5)

The uterine lining sheds, resulting in menstrual bleeding. This marks day 1 of your cycle.

Follicular Phase (Days 6-14)

The body prepares for ovulation by developing follicles in the ovaries.

Ovulation (Day 14-16)

An egg is released from the ovary, marking the most fertile time in your cycle.

Luteal Phase (Days 15-28)

The body prepares for potential pregnancy or the start of a new cycle.
