What is the ovulation period, and how is it calculated?

Learning about your reproductive health is vital for every woman who is planning for a pregnancy. The knowledge is also relevant and extremely useful for those women who want to avoid pregnancy naturally so that they don’t have to go through the depressing process of abortion. A lot of factors are involved during the ovulation period, which lead to pregnancy in later stages.

It is also important to learn about ovulation to ensure that you have a good fertility rate. This article will explore in detail the ovulation process, how to accurately calculate its timing, and different methods to find out your fertility rate.

What is the Menstrual Cycle?

Ovulation is a later stage; the menstrual cycle comes first. It is necessary to learn about this first. The average menstrual cycle is 28 days, and in some cases, there can be a difference of a few days. So, between 21 to 35 days, the majority of women go through the menstrual cycle. Four different phases in this cycle lead to ovulation.

1. Menstrual Phase: The uterine lining sheds, causing bleeding—commonly called periods.
2. Follicular Phase: In this phase, the follicles in the ovary develop and mature.
3. Ovulation Phase: Here, a mature egg is released in the ovary.
4. Luteal Phase: This is post-ovulation time, when the body gets ready for potential pregnancy.

What is Ovulation?

Now, once you know the basics of the menstrual cycle, let’s proceed with the ovulation process. During this period, a mature egg (ovum) is released from one of the ovaries. Then it goes into the fallopian tube, where it remains for fertilization. This is the peak period for women when there are maximum chances of pregnancy. During this period, many ovarian follicles develop under the influence of a hormone called follicle-stimulating hormone (FSH). Among all, only a single follicle becomes dominant and reaches full maturity.

When it ruptures, it releases eggs under the influence of the luteinizing hormone (LH) from the pituitary gland. This egg can survive for around 12 to 24 hours. And if within this period a sperm is present, there are maximum chances that it will fertilize. A sperm can live up to 5 days inside the reproductive tract. Since sperm can survive for up to 5 days inside the reproductive tract, having intercourse in the days leading up to ovulation increases the chances of fertilization when the egg is released.

Now, if you are wondering why this happens and if there is a way to avoid this, then keep reading. We will dive deeper into the ovulation process and later discuss potential methods to avoid this.

When Does Ovulation Occur?

Considering the 28-day menstrual cycle, ovulation usually occurs around 14 days before the next expected period in cases. In a typical 28-day cycle, ovulation usually occurs around 14 days before the next expected period—often around day 14 of the cycle.There can be some differences in days because not every woman has the same menstrual cycle. The timing of ovulation depends on many factors. Like the cycle length, if it’s shorter, then there are chances that ovulation may occur in earlier days. Sometimes, hormonal imbalance can disrupt the pattern, and age is also one of the major factors. It is hard to ovulate at later ages. Stress is another major factor that can delay ovulation, and some medications can also interfere with this process.

The first 14 days of the menstrual cycle are very important to track pregnancy. This is the most fertile window for many women. Also, this is the time when a lot of women prefer to choose contraception or birth control. You can have a tentative idea of your fertile window, when fertilization is most likely to occur.

Calculating Your Ovulation Period

A simple calendar-based approach is best to calculate the ovulation period. There are ample calculators available, but this one is easier.

1. Record the first day of your period for the next 6 menstrual cycles.
2. Note down the shortest and the longest cycle.
3. Now, based on the date picked, minus 18 days from the length of your shortest cycle. You will get the first date of a potential fertile day. For example, if the shortest cycle ends in 26 days, then minus 18, and the 8th of that month is your first most fertile day.
4. Minus 11 from the length of your longest cycle to get the last date of the most fertile day. For example, if your longest menstrual cycle was 32 days, then minus 11, then the 21st is the date that can be your last most fertile day.

This is not reliable for all women because of irregular cycles. But there are more methods to calculate ovulation periods.

Fertility Monitors

This one is an expensive method. There are some available on the market that will track your fertility rate based on a urine sample. Some kits come with a dedicated app that will show you the peak days of your fertility. You can avoid any kind of interaction during the peak period to avoid pregnancy.

Ovulation Predictor Kits (OPKs)

This one is a cheaper alternative to fertility monitors. This kit can predict your peak fertility days if the test is done within 24 to 36 hours. You have to test every day if you are unaware of the peak days. A positive result on a pregnancy test kit indicates that there are maximum chances of ovulation. This is best for women who have irregular cycles.

Basal Body Temperature (BBT) Method

Under BBT, ovulation is tracked via body temperature. It is found that after ovulation, there is a slight increase in body temperature, somewhere around 0.5°F (0.3°C). You don’t need any kit for this, just a thermometer. Note down the readings; you can use a fertility app that has a temperature tracker.

Cervical Mucus Method

This method involves monitoring changes in cervical mucus. It increases and is visible during the fertile period. Usually, after menstruation, the mucus is dry or not noticeable. But before ovulation, it is sticky and cloudy. And in peak time, it is slippery and clear. After ovulation, it turns thicker, or there will be no mucus.

A few body symptoms that can be used to identify ovulation are an increase in libido, breast tenderness, heightened senses, a change in cervical position, and mild pain or cramping. If you are under 35 and unable to conceive after a year, then it is necessary to meet with your doctor. Irregular cycles are also a cause of failure in this process, followed by no period or abnormal bleeding.
