Knowing your safe days is advantageous. Depending on the outcome, you can decide on what days are favourable for intercourse without protection and which ones are not. If you have been wondering how to do your calculations, here is the essential information you require.

What is ovulation?

It refers to when a mature egg (ovum) is released from the ovary. It then moves down the fallopian tube, where it can be fertilised. If sperms (male gametes) are in the fallopian tube when the egg is released, there is a good chance that it will be fertilised, creating an embryo, which will eventually grow into a baby.

When does ovulation start? In an average 28-day menstrual cycle, ovulation typically occurs about 14 days before starting the next cycle.

What are the signs of ovulation?

Ovulation signs are a common thing among women, especially those who have experienced it before. How do you know if you are ovulating? Below are some of the symptoms of ovulation.

Changes in cervical mucus

As you approach ovulation, the body produces more estrogen. As a result, cervical mucus becomes stretchy and clear. Cervical mucus changes help the sperms to swim to the egg that’s released at that time.

Breast soreness or tenderness

This is a common sign of ovulation. It occurs because of the rush of hormones entering your body before and after the ovum is released.

Libido changes

Most women notice that their sex drive increases.

Changes in the cervix

The cervix may become higher, softer, and more open.

Mild pelvic or lower abdominal pain

Some women wonder, can I feel any signs of ovulation? Yes, typically as a mild ache or pain in the lower abdomen, usually on one side or the other.

How long does ovulation last?

Conceiving is only possible if the sperms (male gametes) unites with the ovum. It takes place in the fallopian tube. The best time to get pregnant is the ovulation period that lasts from 3 to 5 days which are between the 13th and the 17th day.

During this time, ovulation occurs, and one or more ova are released from the ovary. The thing is that the ovum can survive for only 11 to 19 hours. But how many days does ovulation last? It lasts for about 6 days. This includes the day of ovulating and five days before it.

The beginning of menstruation is considered the start of the menstrual cycle. The first five days of the period are relatively infertile. However, this is true under the condition that there are no hormonal influences and that ovulation occurred in the previous cycle.

The sixth day of the menstrual cycle is considered possibly fertile. When menstruation is finished, there will come a few days before the ovulation period. After ovulation, the luteal phase starts.

Any woman trying to get pregnant should remember that one cannot be 100% sure that ovulation will occur or not. Another problem is that not many women have regular cycles. If the whole cycle lasts between 22 and 35 days, it is considered normal.

Short cycles are not very common, while longer cycles are often observed in women. The most common cycle length in women is 28 days.

The length of the menstrual cycle is the interval between the two cycles. A new cycle s with the first day of menstruation. The beginning of the cycle is the only point in the cycle that can be easily determined without additional methods and equipment that cannot be said about other menstrual cycle points.

Women also need to understand that there is no such thing as a normal cycle length. Every woman has a unique cycle that sometimes fluctuates from month to month. Moreover, menstrual cycle length can vary throughout life.

In case your cycle length is varying, observe all the changes in your body caused by taking medicines. If you face any difficulties, you can ask the gynaecologist to determine your fertile and infertile days.

How to calculate ovulation for pregnancy

If you are trying to get pregnant, you need to pay attention to timing, but the truth is that it is almost impossible to calculate the precise time of ovulation. Remember that ovulation can’t be determined accurately.

There is widely-spread speculation among women that the fourteenth day of the cycle is the most fertile, but it is actually not true. Recognizing fertile days without special tests or additional examinations is not easy. Pregnancy computers determining the temperature and consistency of cervical mucus are not the sure ways to determine fertile days.

To establish a safe period, different methods can be used. Ovulation calculation is one of the most popular ways to determine the fertile and infertile days and each cycle's length. When using an ovulation calculator, you need to enter the latest menstruation date, and it will show the ovulation and safe days.

Unfortunately, the ovulation calculator cannot be used solely as a natural birth control method because different external factors can influence the results. Therefore, to be safe from unwanted pregnancy, it is better to use it together with other methods, such as the symptothermal method and calendar method.

  • Fertile days - Possible to get pregnant.
  • Infertile or safe days - Not possible to conceive.
  • The luteal phase - When it is possible to conceive a baby.

The safe period calculator can be used by women whose average length of the menstrual cycle for the past six months has been between twenty-five and thirty-five days. Also, the difference between the shortest and longest cycles should be less than seven days.

The calendar method or the rhythm method is named after doctors Knaus and Ogino. In this method, information is obtained mathematically. It is important to remember that you cannot rely on this method's results if you have used it for less than 6 months. The calendar method is actually not considered 100% reliable because it neglects bodily signs (temperature and hormones).
