Menstrual Cycle Timing: How Long Until Your Next Period?

You cannot get a period immediately after one ends. Menstruation involves shedding the uterine lining, a process that typically occurs every 21–35 days (average 28 days). After a period ends, the uterus begins rebuilding its lining during the follicular phase, which usually takes about 14 days before ovulation occurs and the next cycle can begin.

Cycle length varies by individual and can change due to stress, hormones, age, and health conditions. Tracking your cycle helps predict your next period more accurately.
