FAQs about Menstrual Cycle Length
1. Why does my cycle length vary?
Small fluctuations (2-3 days) in your cycle are normal and can be caused by stress, travel, illness, or changes in diet or exercise. Larger variations might indicate hormonal imbalances and should be discussed with a doctor.
2. Can I use the calculator for irregular cycles?
Yes, but predictions may be less accurate. For irregular cycles, track your periods for 6+ months to identify patterns. If cycles are extremely unpredictable, consult a healthcare provider.
3. When is my period considered late?
Your period is late if it doesn’t arrive within your usual cycle range. For example, if your cycle is normally 28 days and you’re on day 32 without bleeding, it’s late. Common causes include stress, pregnancy, or hormonal changes.
4. Does the menstrual cycle length affect fertility?
Very short (<21 days) or long (>35 days) cycles may impact ovulation frequency. Tracking helps identify fertile days if you’re trying to conceive. Irregular cycles warrant a doctor’s evaluation for underlying issues.
5. Can birth control change my cycle?
Yes! Hormonal contraceptives often regulate, shorten, or even stop periods. It may take 3-6 months for cycles to normalize after stopping birth control.
