How to calculate the safe period for women, detailed explanation of the safe period calculation method
A woman’s safe period refers to a period of time after a woman’s menstrual period, which is a period when sexual intercourse is less likely to lead to pregnancy. For women who do not want to become pregnant, it is very necessary to calculate the safe period scientifically and reasonably. So, how to calculate the safe period for women? The safe period calculation method is explained in detail from four aspects below.
Understanding the menstrual cycle is the basis for calculating the safe period
Every woman\’s menstrual cycle is different, so you must first understand your menstrual cycle before you can calculate the safe period. The menstrual cycle is measured from the first day of your period until the first day of your next period. The normal cycle is 28 days, but there are also cases around 25 and 35 days, and in rare cases the cycle can even be as long as 45 days. Therefore, correctly understanding your menstrual cycle is the basis for calculating safe periods.
Determine menstrual cycle by calculation
If you haven\’t paid attention to your menstrual cycle, you can calculate it in the following way: record the date when the first menstrual period begins, and then look at the date when the next menstrual period begins. The number of days between the two dates is the length of the menstrual cycle.
Calculate the starting time of the safety period
For example, if your menstrual cycle is 28 days, the safe period starts on day 8 of your menstrual cycle. If your menstrual cycle is 35 days, the safe period starts on day 11 of your menstrual cycle. Otherwise, if your menstrual cycle is 25 days, the safe period starts on day 9 of the menstrual cycle.
Calculate the end time of the safety period
The end of the safe period is two days before the start of your period, so you need to reserve two days for confirmation. For example, if your menstrual cycle is 28 days, the end of the safe period is between day 19 and day 26 of the menstrual cycle. If your menstrual cycle is 35 days, the end of the safe period is between day 22 and day 30 of the menstrual cycle. If your menstrual cycle is 25 days, the end of the safe period is between day 13 and day 17 of the menstrual cycle.
Things to note when calculating the safety period
Although understanding the menstrual cycle and calculating the safe period seem to be very simple problems, in actual operation we still need to pay attention to the following matters:
The menstrual cycle changes frequently
Every woman\’s menstrual cycle fluctuates from time to time and may not be the same every month. Therefore, it is best to record menstrual cycles for 3-6 months to calculate an average menstrual cycle to more accurately predict the safe period.
Accurate prediction of menstrual period is very important
The accuracy of calculating the safe period based on the shortest menstrual cycle and the longest menstrual cycle is high, so it is very important to accurately predict your menstrual period and record the menstrual date regularly.
Overtime and early menstruation \”surprise\”
Unstable menstrual cycles, sudden overtime or advance will affect the calculation of the safe period. At this time, the safety period needs to be recalculated, and correctly avoid the dangerous period before having sex.
Other important matters that should be paid attention to during the safety period
In addition to menstrual cycles and calculations, there are the following things to note:
The safety period is not absolutely safe
Although the safe period has been accurately calculated to avoid the peak period of pregnancy, it is not 100% safe. If you want to be safer, it is best to use it in conjunction with other contraceptive methods.
Some diseases and drugs will affect the safety period
Some diseases and medications can affect the menstrual cycle and therefore affect the calculation of the safe period. You need to consult your doctor based on your own situation.
Standards and calendars are the most basic tools
Criteria and calendars are the most basic tools for calculating safe periods, so it is best to have the corresponding tools at home and learn how to use them after surgery.
Summary
Understanding the menstrual cycle, calculating the start and end times, and precautions are some basic methods for calculating a woman\’s safe period. However, the safe period is not a 100% contraceptive method. We still need to pay attention to other contraceptive methods that need to be used in combination, the impact of diseases and drugs, and the preparation of appropriate tools.
