SHELY Care is in early access. Cycle tracking is for awareness — not a diagnosis, not contraception, and not medical advice.

The cycle

Four phases, one rhythm

A typical cycle moves through four phases. Day ranges below are illustrative for an average ~28-day cycle — yours may be shorter, longer, or irregular, and that's worth understanding too.

Menstrual

Days 1–5

Your period. The uterine lining sheds. Energy can dip — rest is reasonable.

Follicular

Days 1–13

Hormones rise as an egg matures. Many people feel energy returning.

Ovulation

Around day 14

An egg is released — the most fertile window. Cycles vary, so this shifts.

Luteal

Days 15–28

The body prepares for a possible pregnancy. PMS symptoms can show up here.
