How to know your safest period for pregnancy as a woman

Understanding your safest period for pregnancy is crucial for women who want to plan their family or avoid an unplanned pregnancy. The menstrual cycle plays a significant role in determining fertility, and tracking ovulation can help identify the most fertile days. By understanding your menstrual cycle and tracking ovulation, you can identify the safest periods to engage in sexual activity without the risk of getting pregnant. In this article, we will explore how to understand your menstrual cycle, track ovulation for pregnancy, and identify your safest periods.

Understanding Your Menstrual Cycle

To know your safest period for pregnancy, it is essential to understand your menstrual cycle. The menstrual cycle consists of several phases: menstruation, follicular phase, ovulation, and luteal phase.

As a lady who has started seeing your period, you need to know that menstruation is likely to happen every month except if you are already pregnant or breastfeeding. Menstruation comes with blood coming out from your vagina, pain, and other minor symptoms, every month. The period when the bleeding lasts is known as the menstrual duration — it can be between 3 and 5 days in most cases and in a rare case up to 7 days.

The period between two menstruations is called menstrual cycle length. If you are able to know your own and it is fairly constant every month, then you will benefit more from this write-up. On average, a menstrual cycle lasts about 28 days, but it can range from 21 to 35 days. The first day of your period marks the beginning of a new cycle. After menstruation, the follicular phase begins, where the body prepares for ovulation.

On the other hand, some people can see theirs more than twice a month and it will intermittently go up to two months without seeing their period and it will not be because they are pregnant or breastfeeding.

In this case, it is irregular. The main goal of this write-up is for those with regular cycle length to learn when to avoid unprotected sex which may lead them to get pregnant. Also, aside from monthly menstruation, there is also a process that leads up to the release of eggs by women. This is called ovulation. It is important to know that without ovulation, there will be no pregnancy.

Good enough, the time it can happen can be predicted correctly. However, predicting it correctly is possible only among those whose menstrual cycle length is fairly constant. Those who can predict their next menstruation correctly through the help of their menstrual calendar. This ovulation mostly happens in the middle of your menstrual cycle. This is to say that if you have a 28-day cycle, you may ovulate on the 14th day from the day you saw your menses first.

This egg that will be released during ovulation will only stay up to 24 hours. After that, it will be dead and cannot produce pregnancy. However, the sperm from men is not like the egg that can die quickly within 24 hours, the sperm can stay up to 3 to 5 days in the body of a woman. It can be there waiting for you to ovulate for it to fertilize the egg. Do you see the temptation here?

Tracking Ovulation for Pregnancy

Ovulation is the key to determining your safest period for pregnancy. Ovulation occurs when an egg is released from one of the ovaries, making it available for fertilization. To track ovulation, you can use various methods such as tracking your basal body temperature, monitoring changes in cervical mucus, or using ovulation predictor kits. Basal body temperature rises slightly after ovulation, so tracking this daily using a thermometer can help identify your fertile window. Cervical mucus changes during ovulation, becoming clear, slippery, and stretchy. Ovulation predictor kits detect the surge in luteinizing hormone, which indicates imminent ovulation.

Detailed explanation: Identifying Your Safest Periods

To identify your safest periods for pregnancy, you need to understand when you are most likely to be fertile. Typically, the fertile window occurs a few days before ovulation and lasts for around six days. Since sperm can survive in the female reproductive system for up to five days, having intercourse a few days before ovulation can lead to pregnancy. On the other hand, the chances of getting pregnant decrease significantly outside the fertile window.

If you have a regular 28-day cycle, the safest period for pregnancy would be from day 1 to day 8 and from day 19 to day 28, considering ovulation typically occurs around day 14. With the above said, it means that to avoid becoming pregnant, you need to give yourself some days leading up to and after the middle point of your menstrual cycle as that is the time you are likely to ovulate. If you have a 28-day cycle, you will have the 14th as the middle point.


Before you go deeper into this piece of article, let me disclaim that this piece of article is made mainly for those with regular(fairly constant) menstrual cycles. If you are emotionally stressed or under drugs that may change your cycle length, this may not work for you. It will work for you if you already know how to use the calendar method for your menstruation and ovulation.

This means that you have to give yourself at least 3 days before the day 14th from the day you started seeing your menstruation and also a minimum of 3 days after the day 14th. With the above said, it means that you have to give yourself from 11th to 17th as your unsafe period with high risk for pregnancy — period you can easily get pregnant.

These are the days that you are likely to ovulate or have a sperm remain viable in your body to meet your ovulated egg. This means that from the 11th day till the 17th day, counting from the first day you saw your menstruation, you should not have unprotected sexual intercourse.

If you do, you may get pregnant. The chance of getting pregnant those days is high. Other days apart from the 11th to the 17th day are your safe period. You can engage in sexual intercourse with or without protection.

Moreover, if you are not living with your partner(husband or wife) and you are not sure of their status, you may have to be careful not to contract venereal diseases like HIV, Hepatitis B, and C, Human Papillomavirus, etc. You can prevent them by using protection like condoms. This is because these ones are deadlier than just being pregnant.
