‘Safe period’ suggests the days when a woman has less chance of getting pregnant. If you are not planning to have a baby and wish not to use contraception methods, this is the best time to plan on having intercourse with your partner.
A safe period is the time during which there is no egg present for the purpose of fertilization. This brings down your chances of getting pregnant. If you engage in sexual relations when there is no egg, you can’t get pregnant because this is the infertile period in a menstrual cycle.
To understand the safe period better, you must first understand the menstrual cycle. Most women are usually fertile around their ovulation phase which starts around 14 days before your period starts.
If you have a fairly regular menstrual cycle of around 28 days, it gets easy to pinpoint the time when you will be highly fertile. For most ladies, ovulation happens roughly 14 days before the following menstrual cycle begins.
The week after the first week of your period is generally considered safe period but some women may risk getting pregnant when they have sex on day 1 or day 2 of their periods (1).
In a menstrual cycle of 28 days, you must avoid having sex from day 9 to day 16 since these will be highly fertile days. Fertile period is the time when you have a higher chance of getting pregnant (2).
It is important to remember that safe period is always not the best way to avoid pregnancy. If you wish to avoid pregnancy altogether, contraceptives may still be your best bet. There is no part of a period cycle that will ensure 100% that you won’t get pregnant.
The first step to understanding the most safe period to have sex while avoiding pregnancy is to understand your menstrual cycle and how it works.
A standard menstrual cycle can be divided into four stages – menstruation, the follicular stage, i.e. pre-ovulation stage, the ovulation stage, and the luteal stage, i.e. post-ovulation stage). The cycle days for each of the stages mentioned below refer to a standard 28-day cycle. Your cycle days may vary if you have different durations or irregular menstrual cycles.
The menstruation phase or the periods last for 3 to 5 days in most women, sometimes for up to 7 days in some women. This is the time when the uterus lining from the previous cycle sheds and leaves the body in the form of blood and mucus. Your standard menstrual cycle is calculated from day 1 of your periods. The chances of getting pregnant when having sex during this period are very minimal though not impossible.
The menstruation phase also forms a part of the follicular phase since the follicles that carry eggs start forming and maturing.
This phase starts from day 1 of the menstrual cycle and lasts up to day 14 just before ovulation starts, hence the name pre-ovulatory phase (3). This phase contains the safe days which can last between day 3 to day 9 of the menstrual cycle.
This is the stage when ovulation happens. A well-developed ovarian follicle bursts and releases an ovum, otherwise called an egg. The time just before and after the ovulation is known as the ovulation stage.
The ovulation phase is the most fertile phase (4). Women who are planning to have a baby should plan their intercourse around this time while those who do not want to get pregnant must avoid sex at this time.
This phase usually starts about 2 weeks before your next period. It is difficult to pinpoint when your ovulation will occur.

The luteal phase is the last stage of the menstrual cycle. During this stage, the dominant follicle transforms into corpus luteum in the absence of fertilization resulting in pregnancy(5). This ultimately results in the woman getting her period bleed due to the degradation of the corpus luteum.
The luteal phase carries a lower chance of getting pregnant but having sex during this phase can still cause you to get pregnant in rare cases.
From the above break-up, it is clear that the week leading up to ovulation and the week after ovulation carry a higher chance of getting pregnant. The other weeks have a lower chance. But, it must be noted that safe period is not a sure shot method to avoid pregnancy.
The first step to calculate the safe period for avoiding pregnancy is to chart your menstrual cycle for a few months, say 6 to 8 months. Note the first day of your period for each month and how long each menstrual cycle lasts. This will give you the average length of your menstrual cycle. Based on this data, you can calculate your safe period by following the steps mentioned below.
Based on these calculations, in any given menstrual cycle, you will be highly fertile between day 8 and day 21. While this is just an example, you can follow this method to calculate your safe period to avoid pregnancy.
It is vital to remember that a woman’s cycle and the various menstrual phases may vary from one cycle to another. If you are truly planning to avoid pregnancy, relying just on the safe period may not give you 100% results. Contraceptives are the safest way to avoid pregnancy.
Calculating your safe period is beneficial in light of the fact that it will enable you to comprehend what days it is excellent to engage in sex without the assurance and with no pregnancy alarms. Realizing how to figure out your safe period is fundamental if you don’t wish to have a baby immediately.
However, the safe period calculator is an incredible strategy for contraception since it doesn’t include utilizing an IUD, ingesting hormonal birth control pills, or hormone infusions that can affect various ladies, running from extraordinary emotional episodes to weight gain and different issues that hamper one’s prosperity.

Fertility Awareness, otherwise called natural family planning, is a method for foreseeing safe period days. Fertility awareness methods involves observing parameters such as basal body temperature and cervical mucus or charting calendars to monitor cycles or use a combination of both methods to calculate the safe period (6).

FAMs or fertility awareness methods can be of three different types – symptoms-based methods, calendar-based methods, and a combination known as the sympto-thermal method.
Symptoms-based FAMs rely on your body’s symptoms and behavior to calculate your most fertile days. Once you are aware of your fertile days, you can avoid sex on these days. Symptoms-based FAMs include
Basal body temperature relies upon your internal body temperature which you have to chart and track to know when you ovulate (7). There will be a rise in temperature if you are ovulating.
The presence, appearance, and consistency of your cervical mucus will change throughout your menstrual cycle. Observing these changes can help you track your safe days (8).

Calender-based fertility awareness methods are based on calendar calculations and need regular tracking and charting for a few months. These are of two types.
The calendar method helps you chart your ovulation and safe periods. You will have to track your periods consistently for 6 to 8 months to be able to pinpoint your ovulation and safe periods.
The standard days method follows a similar tracking pattern to calendar method. This method is useful only for women who have fixed period cycles with standard length across most months. According to this method, the period between day 8 and day 19 of a menstrual cycle is considered safe period (9).
The sympto-thermal method is the most effective technique since it is a mix of all the above-mentioned methods. It includes body temperature, Ovulation Method, Rhythm Method alongside following cervix changes, breast tenderness, slight spotting, abdominal heaviness, and mild abdominal pain.
Fertility awareness methods may not be a sure-shot way of avoiding pregnancy. Calculating safe period days is not a 100% reliable way to help prevent pregnancy. Even though a few women depend on their reliability, there is a decent possibility of disappointment as your periods may get irregular or some unexpected hormonal changes may happen that you may not know about. You are bound to expand your odds of not falling pregnant during safe period days that lessen the potential risk.
Here are a few steps to follow when employing safe period and FAMs as a way to avoid getting pregnant.

It will require you to enter data such as the first day of your period cycle over a period of a few months.
You can utilize these tools if the average duration of your menstrual cycle from the previous 6 to 8 months is in the range of 26 to 32 days, and the difference between the most limited and most extended cycles is seven days or less.
