🧬 Ovulation & Fertile Days Calculator

📘 Ovulation Calculator: Understand Your Fertile Window

A Ovulation Calculator is a valuable fertility tool that helps women estimate when they’re most likely to conceive. It calculates ovulation and fertile days based on your menstrual cycle length and the first day of your last period.

🧠 What is Ovulation?

Ovulation occurs when your ovary releases an egg, typically 14 days before your next period. This is the time when you are most fertile. If the egg is fertilized by sperm during this window, pregnancy is likely to occur.

📅 How the Calculator Works

• You input your last period date
• You specify your average cycle length (usually 28–32 days)
• The tool estimates your ovulation date (cycle length – 14)
• It highlights your fertile window: 5 days before ovulation and the day of ovulation
• It shows the safe period for natural family planning

📊 Fertile Window

The fertile window is typically 6 days long — ending on the day of ovulation. Sperm can survive inside the female body for up to 5 days, while the egg survives for up to 24 hours. Having intercourse during this window increases chances of conception.

🔍 Example

If your LMP was May 1st, and your cycle is 28 days:

• Ovulation Day: May 15th
• Fertile Window: May 10th to May 15th
• Next Period: May 29th
• Safe Days: Before May 10th and after May 17th
