Period Due Date Calculator — Track Your Menstrual Cycle
Predict the start dates of your next periods, track your menstrual cycle length, and easily identify potential hormonal irregularities with our clinical tracking tool.
The menstrual cycle is a complex series of natural hormonal changes that prepare the female body for potential pregnancy every month. A cycle is clinically measured from the first day of one period (menstruation) to the first day of the next. While the global average cycle length is 28 days, a normal, healthy cycle can range anywhere from 21 to 35 days. Accurately tracking your cycle is not just about avoiding surprises; it is a vital diagnostic tool for monitoring your overall endocrine health. Using our Period Due Date Calculator, you can forecast your upcoming menstrual cycles months in advance. Consistent tracking makes it significantly easier to spot irregularities—such as missed periods, abnormally long cycles, or sudden shifts—which are often the earliest warning signs of underlying conditions like PCOS or thyroid dysfunction.

Awaiting Inputs
Please fill in your last period date, average cycle length, and period duration on the left to calculate predicted due dates.
How to Use This Calculator
Predicting your next period is fast and simple. Follow these steps:
- Enter the Start Date of Your Last Period: Select the exact date on the calendar when your most recent menstrual bleeding began (Day 1 of your cycle).
- Enter Your Average Cycle Length: Input the average number of days between the start of one period and the start of the next (e.g., 28 days).
- Enter Average Bleeding Duration: Input how many days your period typically lasts (usually between 3 to 7 days).
- Calculate: The calculator will project the exact dates of your next several periods and highlight your estimated fertile windows based on your cycle.
What Your Result Means
Your results will show the projected start dates for your next menstrual cycles. The mathematical model assumes your hormones function consistently. Your cycle passes through four distinct biological phases before reaching your predicted due date:
1. Menstruation
The active shedding of the uterine lining (endometrium). This typically lasts 3 to 7 days and marks the beginning of the new tracked cycle.
2. Follicular Phase
Estrogen levels rise significantly as ovarian follicles mature. This phase prepares the body for ovulation and rebuilds the uterine lining.
3. Ovulation
The release of a mature egg from the ovary. It typically occurs exactly 14 days before the start of your *next* expected period.
4. Luteal Phase
Progesterone peaks. If fertilization does not occur, hormone levels crash, which triggers the onset of your next calculated period.
When to See a Doctor
If the dates predicted by the calculator are consistently wrong month after month, you likely have an irregular menstrual cycle. This means the interval between your periods falls outside the healthy 21–35 day range, or varies wildly by more than 7–9 days each month. You should consult a gynecologist immediately if your periods stop entirely for 3+ months (amenorrhea), if you bleed heavily for more than 7 days (menorrhagia), or if you experience severe, debilitating pain during menstruation (dysmenorrhea).
These irregularities are the primary clinical red flags for serious endocrine disorders such as Polycystic Ovary Syndrome (PCOS), Endometriosis, Thyroid dysfunction, or uterine fibroids. At Prakash Hospital, our expert Gynecology department in Noida provides comprehensive transvaginal ultrasounds, full hormone panels (FSH, LH, Prolactin), and personalized clinical management to restore your cycle.
