Within this range, variation from cycle to cycle is also normal. Most people with regular cycles see 2–7 days of variation cycle to cycle. A person whose typical cycle is 28 days might have cycles ranging from 25 to 31 days across a year without any underlying problem. What counts as "late" depends on your personal baseline: If your typical cycle is 28 days and this one is 32 days: 4 days late — within normal variation If your typical cycle is 28 days and this one is 42 days: 14 days late — requires explanation If you have no established baseline (you've never tracked), "late" is harder to define By Days Late: What's Usually Going On 1–7 Days Late Within or near normal cycle to cycle variation for most people.
