Before Your Visit: Period Details to Bring

What cycle dates should you write down?

Cycle dates are the backbone of any menstrual history. Note the first day of your last few periods and how many days each lasted, since clinicians count from the first day of bleeding to the first day of the next period. Most adult cycles run about 24 to 38 days apart and last up to roughly 8 days, and a committee opinion from ACOG recommends recording this pattern as a vital sign 1Ref 1American College of Obstetricians and Gynecologists (2015).ACOG Committee Opinion No. 651: Menstruation in Girls and Adolescents: Using the Menstrual Cycle as a Vital Sign.ACOG committee opinion establishing the menstrual cycle as a vital sign and defining normal adult cycle frequency (about 24-38 days) and duration (up to roughly 8 days) that a period history should capture.. A simple note or a period-tracking app is enough. If your cycles swing widely, that variability is itself useful data, and irregular cycles or perimenopause can both change the rhythm in ways worth flagging.

How do you measure and describe your flow?

Flow is easier to describe with concrete counts than with words like light or heavy. Track how many pads or tampons you use on your heaviest days, how often you change them, and whether you pass clots or leak overnight. The Office on Women's Health notes that soaking through a pad or tampon every 1 to 2 hours, or bleeding longer than 7 days, points to heavy menstrual bleeding worth evaluating 2Ref 2Office on Women's Health (U.S. HHS) (2025).Period problems.Office on Women's Health guidance that soaking a pad or tampon every 1-2 hours, or bleeding beyond 7 days, signals heavy menstrual bleeding worth evaluating.. A photo of a menstrual cup's markings or a tally on your phone both work well. This kind of detail helps a clinician gauge blood loss and decide whether iron testing makes sense.

Which symptoms and their timing matter most?

Symptom timing often reveals more than the symptoms themselves. Log pain, mood changes, headaches, bloating, and fatigue alongside the cycle day they appear, because a pattern that tracks the days before or during bleeding narrows the possibilities. Pain that disrupts work or school can signal painful periods rather than ordinary cramps, and about 1 in 10 women of reproductive age has endometriosis, according to the World Health Organization 3Ref 3World Health Organization (2025).Endometriosis (fact sheet).WHO fact sheet stating endometriosis affects roughly 10% (about 1 in 10) of reproductive-age women and commonly causes painful periods.. Note what relief you have tried and whether it helped. Fatigue that lingers may reflect low iron, which a ferritin test can help clarify 4Ref 4MedlinePlus (National Library of Medicine) (2025).Ferritin Blood Test.MedlinePlus explanation of the ferritin blood test as a measure of iron stores, commonly checked when heavy periods raise concern for iron deficiency.. Even a rough handwritten note beats memory here, because cycle-to-cycle patterns are easy to forget between visits.

What records and medications should you gather?

A short list of records saves guesswork at the visit. Helpful items to gather include: - Names of prescriptions, hormonal birth control, pain relievers, and supplements you take - Any bloodwork or ultrasound reports from the last 12 months - A one-line summary of prior period treatments and whether they worked

Adolescents may want a parent's memory of when periods began, while women in their 40s can note early perimenopausal shifts. Heavy or disruptive bleeding is common across these life stages, so listing what has already been tried gives the visit a running start rather than a blank slate. A brief written timeline also spares you from reconstructing years of history on the spot, and it lets the clinician spot trends you might not notice yourself.

When your period history needs a clinician

A clinician can turn your notes into a plan. Sharing cycle dates, flow counts, symptom timing, and your medication list lets a primary care clinician or gynecologist judge whether labs, imaging, or a treatment trial fits your situation. Bring questions too: what your bleeding pattern suggests, whether iron or thyroid testing is warranted, and which options match your goals. Gale can help you organize these details before the visit. Writing your top 2 or 3 questions at the top of the page keeps them from slipping your mind once the appointment gets busy. If bleeding ever soaks through protection every hour for several hours or leaves you dizzy, that is a reason to seek same-day care rather than wait for a routine slot.
