Evidence-Based Assessment

Is My Cycle Normal?

Answer a few questions about your period and cycle to find out what's normal, what's a normal variation, and what's worth discussing with your doctor.

Step 1 of 8

How old are you?

Your age group matters because what's "normal" changes through the different stages of your reproductive life.

Step 2 of 8

How many days is your cycle?

Count from the first day of one period to the first day of the next period. If your cycle varies, give your best estimate of the usual length.

Step 3 of 8

How regular is your cycle?

Think about the past 6-12 months. Does your period come roughly on schedule, or is it unpredictable?

Step 4 of 8

How many days does your period last?

Count all days of bleeding, including light spotting days at the beginning or end.

Step 5 of 8

How heavy is your flow?

Think about your heaviest day. There are no wrong answers — everyone's "normal" is different, and most women have never been told what's actually normal.

Step 6 of 8

Do you experience any of the following?

✓Large blood clots (bigger than a quarter / 2.5 cm)Small clots are normal — large ones may not be

How painful are your periods?

Rate your worst cramping pain, typically on the first 1-2 days of your period.

Step 8 of 8

✓Acne, excess facial/body hair, or thinning scalp hairMay suggest excess androgens (male-type hormones)
