Calculating a woman's fertility after menstruation

Pregnancy is a matter of time. The right time in which male sperm cells meet an egg from a woman then conception occurs. In order to get pregnant quickly, you can guess when your fertile period and infertility occur. But how do you calculate fertility?

Estimating and calculating a woman's fertile period after menstruation is one of the main ways to have offspring. That is why to plan a pregnancy, you need to have a record of your menstrual period.

What is the menstrual cycle or menstruation? Menstrual cycle is the range of days from the first day of menstruation until the first day of the next menstruation. A normal menstrual cycle is every 21-35 days. Day 1 (one) of the menstrual cycle is the first day of menstruation.

Understanding Women's Fertility

When does menstruation begin? Menstruation starts on the first day when the uterine wall decays and comes out with blood from the vagina. During menstruation, the egg cells will develop in the ovary. When the egg is cooked, the ovary will release the egg, this event is called ovulation.

When does ovulation occur? Generally, ovulation occurs around 12–14 days before the first day of your next period. Actually, the day when ovulation depends on your menstrual cycle. If your cycle is short, for example, only 22 days, ovulation can occur only a few days after your period ends. So, the time of ovulation can be different for each woman. For this reason, it is important for you to know your menstrual cycle in order to estimate the time of ovulation.

So, when is a woman's fertile period? Your fertility period ranges around the time of ovulation, about five days before ovulation occurs. Generally, a woman's fertile period is 12-16 days before the next menstrual period. In other words, the average woman experiences a fertile period between the 10th day and the 17th day after the first day of her last period. This applies to women who have a regular menstrual cycle of 28 days. However, if your cycle is different, you can learn and calculate when your fertility period.

The challenge is the length of a woman's menstrual period can change from time to time, usually lasting 2-7 days. This condition makes ovulation differ a week faster or slower than the previous period.

Apart from ovulation, pregnancy is also very much determined by the process of sperm reaching the egg. In order to get pregnant, these mature eggs must be fertilized within 12 to 24 hours.

Calculate Your Own Fertility

The egg must be fertilized within 12-24 hours after ovulation. Because of that, it is important to detect in the days whether the woman is in the most fertile condition. Generally, this fertile period is calculated based on records and analysis of menstrual cycles for at least the last 8 months.

Estimates of fertility can be calculated by the following formula:

  • Know your shortest cycle. For example: 27 days. Reduce this number by 18. The result: 9. This number is the first day when you are in the most fertile position.
  • Know your longest cycle. For example: 30 days. Reduce this number by number 11. The result: 19. This number is the last day when you are most fertile.

Thus if your average cycle is 27-30 days, then you will be most fertile on days 9 to 19.

Indicator of Women's Fertility After Menstruation

To further strengthen the predictions of the most fertile days, you can use several other indicators, such as:

  • Increased basal body temperature
  • Basal body temperature is body temperature when you wake up in the morning. The normal temperature is 35.5–36.6 degrees C. But if your body temperature rises slightly higher than that number, this can mean you are ovulating.
  • The presence of mucus from the cervix
  • The mucus that comes out of the cervix can have a runny consistency until this change in mucus shows changes in the hormone levels of estrogen in the body, which also signals whether ovulation is imminent. In the fertile period, the mucus is clear, slippery and elastic, like raw egg white. This liquid will facilitate and protect the path of sperm to the uterus to meet the egg.
  • Mild to severe pain in the abdomen or one part of the back
  • Some women feel this around ovulation. This pain can also be used as a sign to help detect fertility.
  • Feeling more passionate
  • Some women feel more passionate, more excited, and easier to socialize when experiencing fertility.

When is a woman's infertile period?

Simply put, your infertility is a day that is not included in your fertile period. For example, if according to calendar calculations (as in the example above) your fertility period lasts for days 7-18 after the first day of menstruation, then your infertility is a day other than that day in the menstrual cycle (starting from day 19 onwards until you menstruation again).

Your chances of getting pregnant on the first day of menstruation are almost zero percent. A few days later, it may still be your infertile period. But make no mistake, your chances of getting pregnant are still open, although the likelihood is low. Back again, nobody knows when ovulation occurs.

After the egg is not fertilized and decays (menstruation), your body will then prepare to release the egg again. So, your fertile period will then come back again and your chances of getting pregnant increase again.

By estimating and calculating the fertile period after menstruation, and understanding what happens during the menstrual cycle, you will become more helpful in planning a pregnancy and evaluating reproductive health. If you are still struggling, you can consult your obstetrician to determine your fertility period.
