The safe period is within a few days after the menstrual period ends.

The safe period is divided into the safe period before ovulation and the safe period after ovulation. The period from the end of menstruation to the day before ovulation is the safe period before ovulation.

From the first day after the end of ovulation to the day before the next menstrual cramps is the safe period after ovulation. The safe period after ovulation is safer than the safe period before ovulation. This is because some women sometimes affected by environmental changes and mood swings affect the advance of ovulation, thus before the safe period of ovulation will be shortened.

The seven days before menstruation and eight days after menstruation are the safe period for adult women, which is a calculation method used by most people for contraception. In addition to the calendar method that uses days to calculate, there are also the basal body temperature method and the secretion observation method. However, the safe period is not absolutely safe. Sometimes women ovulate earlier or later, and the judgment of the safe period becomes invalid at this time.

Contraception during the rhythm period is unsafe. Extrapolation is often unreliable. The time of female ovulation is affected by factors such as the external environment, climate, her own mood, and health status, which may result in delayed or early ovulation, and extra ovulation may also occur. The failure rate of safe period contraception is about 20%. Generally, people with irregular menstrual cycles are not suitable for using the safe period method for contraception.

Warm reminder: Generally, the 8 days after menstruation is over are the safe period, but it is unsafe to use this method for contraception, so more effective contraceptive methods should be used to avoid some unnecessary troubles.
