Ovulation Calculator

To increase your chances of conceiving a child, becoming familiar with your unique menstrual cycle is crucial. You can use our 100 percent accurate ovulation calculator, to figure out when you’re most fertile: when your period is due, when you should take a pregnancy test, and when you’d be due if you conceived on any of those specific days.

Ovulation occurs when a fertilized egg is expelled from an ovary. The average amount of time until your next period starts is 14 days. However, this can vary. To increase your chances of conceiving, you should become familiar with your reproductive window.

This article will help you know your most fertile time of the month by tracking your ovulation cycle with our free ovulation calculator.

What is an ovulation calculator?

The Ovulation and Fertility Calculator determine your ovulation date by subtracting 14 days from the expected date of your next menstrual period. If your cycle lasts 28 days, your next period should begin 28 days after the starting day of your previous period.

Your fertile window is the day you ovulate five (5) days before. However, the last three days of this window are the most likely for you to become pregnant.

How To Calculate Ovulation Date

If you want to know when you’re most likely to conceive again, you need only record the first day of your previous menstrual flow or period and count backward nine days. Example: If your last period was on the 18th of November, now count 18, 19, 20, 21, 22, 23, 24, 25, and 26.

Then 27, 28, 29, and 30 are your ovulation or fertile days for a woman with a 28-day menstrual cycle. So during these four days, the system will be highly fertile and ready for conception.

It is recommended that women over 35 have regular sexual intercourse before, during, and after ovulation or fertile days to increase their chances of conceiving.

If you follow these for three or four months without becoming pregnant, please see your doctor for proper dianosis and medical advice.

8 Common Signs Of Ovulation

Every woman’s ovulation is different and unique, regardless of race, culture, or age. To be sure, there are a few universal ovulation indicators that every woman should know:

  1. Your cervical mucus will change during this time, becoming more transparent and stretchier, like the white of an egg (these unusual changes taking place in the cervical mucus will make it easier for sperm to swim to the egg).
  2. During your most fertile days—or rather, ovulation days—your basal body temperature will go up a little and stay high.
  3. Because of changes in your estrogen and progesterone levels, you may experience nausea and headaches while ovulating.
  4. You will also notice changes in the cervix; during this time, the cervix becomes higher, softer, and more widely open.
  5. You will also be seeing some light brown spotting or discharge.
  6. You will start experiencing some sort of mild pain in the pelvis or lower abdominals.
  7. You experience a frequent urge for sex and increased sexual drive.
  8. Your smell organ increases your sensitivity to smell and taste.

What If My Menstrual Cycles Are Irregular?

For women whose menstrual cycles are irregular or of varying lengths, pinpointing their ovulation window can be a challenge. For more information, talk to a fertility specialist for advice or your doctor, but ovulation urine tests and tracking your ovulation may be helpful.

There is no need to worry about infertility if you have recently stopped using oral contraceptives, IUDs, or implants, even for an extended period of time. Those who stop using contraceptives and then get erratic periods should see a doctor.

The average length of a normal menstrual cycle is between 23 and 35 days. If you are worried about changes you experience in your menstrual cycle, you should talk to your doctor or a fertility specialist.

How To Increase Your Chances Of Getting Pregnant

The best way to increase your chances of getting pregnant is to maximize the number of times that your healthy eggs and sperm meet. A woman’s fertility peaks in the days prior to and after ovulation, the time of the month when an egg is released.

Sexual activity can result in pregnancy six days before the usual menstrual cycle.

The five (5) days prior to ovulation as well as the day of ovulation are sometimes referred to as the “fertile window.”

Pregnancy comes on swiftly for some people, but it may take more time for others. The time it takes to conceive is now better understood.

Conception And Sex

Most couples can get pregnant with just a little bit of regular sex (every 2 to 3 days). If you are under 40 and have regular sexual activity without using birth control, you are 80% likely to get pregnant within a year.

Regular sex throughout your cycle increases your chances of getting pregnant because healthy sperm will be ready when the egg is released.

Conception is possible even if you haven’t had intercourse because sperm can live inside a woman’s body for up to 7 days and fertilize the egg when it is released.

If you want to get pregnant, it’s best to try to have intercourse around the time your ovaries are most likely to release an egg, which is usually around the 15th of the month. Don’t stop having sex during ovulation; that’s when you’re most fertile. Fertility will end the cycle after this point.

FAQs about our Ovulation Calculator

How To Calculate Ovulation

To calculate your ovulation window, you must know when you menstruate, which is the exact day your last period started. To do this, you need to keep a record of the date of your next menstrual flow and how long it takes you to have your period (which tends to vary from 23 to 35 days).

To find out when you ovulated, you need to know the length of your menstrual cycle. This is the number of days between the first day of bleeding during your last period and the first day of bleeding during your next period.

Now, subtract 14 days from the end of your current cycle to get a rough idea of when you ovulate.

Keep in mind that making love 1-2 days before you ovulate gives you the best chance of getting pregnant.

How To Calculate Ovulation With Irregular Periods

The optimal timing for ovulation can be predicted if the 32-day cycle is set in stone. The speculative formula may be used for cycles lasting longer than 28 days. The fertile day will add one day for each additional day.

Women whose menstrual cycles are shorter than 28 days have one fewer fertile day than women whose cycles are normal.

For example, it’s easy to see that if a woman’s menstrual cycle lasts 32 days, her fertile period will last from day 15 (11 + 4) to day 20 (16 + 4), and ovulation may happen on day 18 (14 + 4).

How To Calculate Menstrual Cycle And Ovulation

To determine how many days are in your current cycle, you should begin counting on the first day of your period. Keep count for three months and sum up the days. The average cycle length can be calculated by dividing that number by 3.

Your period typically begins 12 to 16 days after ovulation. The length of the second phase of the cycle is consistent across the course of the cycle and averages 14 days.

The length of the cycle depends on how variable the first part is. For example, if your cycle lasts 28 days, ovulation will happen on day 14. The egg is released on day 12 of a 26-day cycle. On day 18 of a 32-day cycle, the egg is released.

Using an ovulation prediction kit is the most accurate technique to pinpoint the day of ovulation. If you take your shortest cycle and subtract 14, you’ll know when you might ovulate. To make sure a full cycle, testing should start two days before the estimated date of ovulation.

What Is Ovulation Period And How Is It Calculated

The number of days that pass between the beginning of the first day of bleeding during one period and the beginning of the first day of bleeding during the subsequent period is the length of your menstrual cycle.

To get a general sense of when you ovulate, take the end of your most recent cycle and deduct 14 days from that number.

Keep in mind that the optimal time for you to have sexual activity is just around the time that you are about to ovulate, which is anywhere from one to two days before you ovulate.

How Long Should I Try To Conceive Before Consulting A Specialist?

If you are under the age of 35, you should try having a baby on your own for 12 months before seeking professional help, and if you are above the age of 35, you should wait 6 months.

A fertility professional can do easy tests to determine what is occurring, explore your choices, and expedite your pregnancy.

How can I recognize the symptoms of ovulation?

In most cases, ovulation will occur between 12 and 16 days before your next period is due to begin. Before trying to conceive, it is helpful to know how long your period typically is.

You might not have ever thought about when you could ovulate during your cycle, and if you’ve been using a hormone contraceptive like the pill, you probably haven’t had a natural cycle in a long time.

Mark in your journal the dates when you bleed throughout your period as a first step. You may calculate the duration of your cycle by calculating the number of days between the first day of your period and the day of your next period.

There are different ways to find out if you’re ovulating, like checking your cervical mucus and temperature or using an ovulation test kit.
