PeriodCalculator.com.ng is Nigeria’s leading period (menstrual) and fertility calculator, built to help women and girls understand their cycles for free without signing up. We believe every woman deserves free, private access to health information about their body.
Our calculators: We built our calculators using standard reproductive health principles, providing you with standard reproductive health principles and giving you quick estimates of your next period, ovulation date, and menstrual cycle.
Every tool we build goes through a careful review process so that you can get clear estimates of your cycles. We’ve kept the design simple, so you don’t need any technical know-how to use them. Just choose your suitable calculator, enter a few details, and get your answer.
Beyond the calculators, we also write articles on menstrual health, fertility awareness, pregnancy, and general women’s wellness. We draw from established medical sources and public health guidance, then break it down in plain language that’s actually easy to read. We keep coming back to update these resources too, because reproductive health information should stay current and useful—not sit untouched for years.
Our Mission
Our mission is to end period poverty, normalize menstruation, and promote menstrual literacy.
Goal
At periodcalculator.com.ng, our goal is to combine women’s health tools and clear health information to help women in Nigeria and around the world easily understand their bodies and make confident decisions about their reproductive health.
Important note: our tools give you estimates based on what you enter, and every woman’s cycle is different. What we offer here is for information and educational purposes only—it’s not a replacement for advice from a qualified healthcare professional. If you have specific concerns about your health, please talk to a doctor.
