Ovulation Calculator: Know how to calculate your Period Date?
Knowing when you ovulate will make it easier to get pregnant.
Following ovulation, the egg that is released can survive for up to 24 hours in the fallopian tube, so having a good supply of sperm is important at this time. Here is how you can determine your ovulation date.
Ovulation Date: An average estimation of your period date
On average, a woman’s menstrual cycle lasts 28 days, starting from the first day of menstruation. So based on a sample 28-day menstrual cycle, ovulation would occur about 14 days before the next period begins. Every woman is different, though, and determining the exact date of ovulation cannot always be calculated according to this average estimation.
Calculate your estimated date of period
The length of the menstrual cycle varies from one woman to another. Some women have a regular 28-day cycle while for others it can be shorter or longer. By subtracting 14 days from the number of days in your cycle, you will get a clearer idea of when you ovulate:
If your cycle is 28 days, ovulation should occur on the 14th day from the first day of menstruation.
If it is longer, such as 32 days, ovulation will take place on the 18th day from the first day of menstruation.
If your cycle varies from one month to another, it gets more difficult to determine exactly when you’ll be ovulating.
There are other methods rather than counting days that help determine the date of ovulation.
Methods to determine the date of ovulation
The temperature curve
Keep a chart and take your temperature every morning when you wake up before getting out of bed or even moving around or eating anything and then record it.
Usually, your temperature varies between 36 and 36.5 degrees Celsius from the first day of menstruation until the date of ovulation and then after that, it rises slightly to about 37 to 37.2 degrees Celsius and remains constant until the following period occurs.
The time of ovulation is positioned just before the temperature increases, so for the first month you know the ovulation date after it has occurred. By keeping track of your temperature for several months you can determine an average and estimate the date of ovulation in the next cycle.
Testing your cervical mucus is an important fertility indicator. Mucus is the liquid that comes from your cervix. Because its texture varies throughout the cycle, you can use it to help to determine when you ovulate. After your period, it is white and creamy, almost like a solid. At the moment of ovulation, it becomes more liquid and stretchy, just like egg whites.
The LH peak
At the time of ovulation, the luteinizing hormone, which is a hormone found in both men and women, is at its peak and triggers ovulation. You can measure your LH level through testing the level in your urine. To do this at home, you can use ovulation test kits found in a local pharmacy.
