What is ovulation?

Ovulation is the process by which a mature egg is released from the ovary. This happens about 14 days before your next period begins. If the egg is fertilized by sperm, it can lead to pregnancy.

Why use an ovulation calculator?

An ovulation calculator can help you predict when you are most likely to ovulate. This information can be useful if you are trying to get pregnant, avoid pregnancy, or simply track your menstrual cycle.

How does an ovulation calculator work?

Ovulation calculators typically use two pieces of information to predict your ovulation day:

The first day of your last period
Your average menstrual cycle length
Once you enter this information, the ovulation calculator will calculate your estimated ovulation day and fertile days.

What are my fertile days or how to predict fertile days?

Your fertile days are the days leading up to and including ovulation day. This is because sperm can live inside a woman’s body for up to 5 days. So if you have sex in the days leading up to ovulation, the sperm could be waiting for the egg to be released.

How to use the free ovulation calculator

To use the free ovulation calculator, simply enter the first day of your last period and your average menstrual cycle length. The calculator will then estimate your ovulation day and fertile days.

Ovulation signs and symptoms

Some women experience signs and symptoms of ovulation. These can include:

A change in cervical mucus. Cervical mucus becomes thinner and more slippery during ovulation.
A slight increase in body temperature.
Mittelschmerz, or ovulation pain. This is a sharp pain that some women experience in the one side of their lower abdomen during ovulation.
Spotting or light bleeding.
Ovulation calculator for irregular periods

If you have irregular periods, it can be more difficult to use an ovulation calculator to estimate your ovulation day. However, there are still a few things you can do to track your ovulation:

Chart your basal body temperature (BBT). BBT is your body temperature at rest. It can rise slightly after ovulation.
Use ovulation predictor kits (OPKs). OPKs detect a surge in luteinizing hormone (LH), which occurs 24-36 hours before ovulation.
See a doctor if you have irregular periods and are having trouble getting pregnant.
