🩸 Hormonal Cycle Symptom Tracker Simulator

Menstrual Phase — Hormones Reset as the Cycle Begins Again

Both hormones bottom out while the uterine lining sheds.

• 3–7 days: Typical duration (Placeholder: varies by person.)
• Low: Estrogen level (Placeholder: near cycle minimum.)
• Low: Progesterone level (Placeholder: near cycle minimum.)
• Cramping: Dominant symptom (Placeholder: prostaglandin-driven.)

What happens during menstruation

Placeholder: lining sheds as hormone support withdraws.

Placeholder: cramping intensity tracks prostaglandin release.

Follicular Phase — Estrogen Climbs as Follicles Mature

Rising estrogen rebuilds the lining and readies an egg.

• ~8 days: Typical duration (Placeholder: days 6–13 window.)
• Rising: Estrogen level (Placeholder: steady upward climb.)
• Flat: Progesterone level (Placeholder: stays low still.)
• Mild relief: Dominant symptom (Placeholder: energy often improves.)

Follicular development and estrogen climb

Placeholder: follicles grow, estrogen output steadily increases.

Placeholder: symptom intensity usually dips this week.

Ovulation — Estrogen Peaks and Triggers Egg Release

A sharp estrogen surge triggers the mid-cycle LH spike.

• Day 14: Typical day (Placeholder: varies with cycle length.)
• Peak: Estrogen level (Placeholder: cycle maximum here.)
• Beginning rise: Progesterone level (Placeholder: starts climbing after.)
• Mittelschmerz: Dominant symptom (Placeholder: brief ovulation twinge.)

The ovulatory estrogen surge

Placeholder: peak estrogen signals the pituitary to release LH.

Placeholder: some feel a brief one-sided pelvic twinge.

Luteal Phase — Progesterone Takes Over After Ovulation

The corpus luteum secretes progesterone to support implantation.

• ~10 days: Typical duration (Placeholder: days 15–24 window.)
• Secondary bump: Estrogen level (Placeholder: smaller second peak.)
• High: Progesterone level (Placeholder: dominant hormone now.)
• Bloating: Dominant symptom (Placeholder: fluid retention common.)

Progesterone dominance in the luteal phase

Placeholder: corpus luteum maintains progesterone until it regresses.

Placeholder: mild bloating and fatigue often appear here.

Premenstrual Phase — Hormones Fall and Symptoms Intensify

Falling estrogen and progesterone drive peak PMS symptoms.

• ~4 days: Typical duration (Placeholder: days 25–28 window.)
• Falling: Estrogen level (Placeholder: sharp late decline.)
• Falling: Progesterone level (Placeholder: corpus luteum regresses.)
• PMS mood/physical: Dominant symptom (Placeholder: combined symptom peak.)

Hormone withdrawal and PMS symptom peak

Placeholder: dropping hormones correlate with peak PMS intensity.

Placeholder: emotional and physical curves both crest here.
