Frequently Asked Questions (FAQ) Period Calculator
Q: How do I calculate my cycle length?
A: To find your cycle length, count the days from the first day of one period to the first day of the next. According to the NHS, a normal cycle length for adults is between 21 and 35 days. (Period Calculator 2026Â )
Q: Why is my period late?
A: While pregnancy is a common cause, other factors include stress, significant weight changes, excessive exercise, or underlying conditions like PCOS. The Mayo Clinic suggests that if your period is more than a week late and you aren’t pregnant, it’s worth consulting a healthcare provider.
Q: Is it normal to have an irregular period?
A: Irregularity is common during puberty and perimenopause. However, for most adults, persistent irregularities should be tracked. Clinical guidelines from the CDC emphasize that tracking your “Day 1” is the most empowering way to identify your unique health patterns.
Q: What are the early signs that my period is coming?
A: Often called PMS (Pre-Menstrual Syndrome), common signs include bloating, breast tenderness, mood swings, and acne breakouts. These symptoms are triggered by the sharp drop in estrogen and progesterone right before menstruation begins. (Frequently Asked Questions (FAQ))
