Menstrual cycle guide: phases, ovulation and symptoms

A simple, non-medical overview of the menstrual cycle, its phases and common symptoms — and why many people use a period tracker to notice patterns.

Phases of the cycle

Menstruation

Bleeding days. The lining of the uterus is shed and a new cycle begins.

Follicular phase

After menstruation, follicles in the ovaries grow and the body prepares an egg.

Ovulation

The egg is released from the ovary. This is the most fertile period of the cycle.

Luteal phase

After ovulation, progesterone increases. Many people feel changes in mood and body (PMS).

What symptoms can be normal

People may notice mild cramps, mood changes, bloating or changes in discharge. Tracking over time can help you see what is typical for you.

If you have concerns

RosyCycle is a wellness tracker, not medical advice. If something feels unusual for you or you are worried, consider talking to a qualified healthcare professional.

How RosyCycle can help
