🩺 Ovulation Calculator – Predict Your Most Fertile Days for Pregnancy
If you’re trying to conceive, understanding your ovulation cycle is one of the most effective ways to increase your chances of getting pregnant. An Ovulation Calculator is a free and reliable tool that helps you predict your most fertile days based on your menstrual cycle.
At Calculators.at, our Ovulation Calculator gives you accurate insights by estimating when ovulation occurs—so you can better plan for pregnancy or track your reproductive health naturally.
🔍 What Is an Ovulation Calculator?
An Ovulation Calculator predicts when your body is most likely to release an egg (ovulate). It uses simple information, like:
- The first day of your last menstrual period
- Your average cycle length (usually between 21–35 days)
From this, it calculates:
- 🕒 Estimated ovulation day
- 📅 Fertile window (the 5–6 days when pregnancy is most likely)
- 📌 Next period start date
🧠 How Does It Work?
Ovulation typically occurs about 14 days before your next period. So if your average cycle is 28 days long, ovulation is likely around Day 14. Your most fertile days are the 5 days before ovulation and the day of ovulation itself, because sperm can survive in the female body for up to 5 days.
Example:
- Last period: June 1
- Cycle length: 28 days
- Estimated ovulation: June 14
- Fertile window: June 9 to June 14
