If your girlfriend has regular menstruation, you may wish to set the cycle to 28 days (most people are around 28 days), then from the day of menstruation plus 14 days (28 divided by 2) is the day of ovulation, 5 days around the day of ovulation is the danger period, and the others are the safe period.
The safe period before ovulation is shorter (it should be a few days of menstruation), and the latter period is longer and relatively safer.
You can do the math according to the specific situation of your girlfriend.
If it's really dangerous, you have to take emergency contraceptive pills such as Yuting or Mifedone tablets within 72 hours, the latest version only needs to eat one, more than a dozen pieces, but for the sake of your girlfriend's body, try to eat as little as possible, there are ***, but 99% of them will not get pregnant after eating.
Hope it helps.

For women who have sex and do not want to have children, it is generally considered that the two time periods other than ovulation and menstruation are safe periods, and it is not easy to get pregnant even if they do not use contraception, and only during the time of ovulation do they temporarily take effective contraceptive measures, this form of contraception is called the safe period contraceptive method.
1.The safe period is unreliable
However, many women have irregular menstrual periods, irregular ovulation periods, and sometimes ovulation bleeding is mistaken for menstrual periods. In addition, there is also a situation that even if the menstrual period is normal once every 28 days, because the follicle growth period and luteal secretion period may be shortened or prolonged, the ovulation rock cherry blossom cultivation period may not be about 14 days before the next menstrual period, and some people may even ovulate and conceive during the menstrual period.
2.The calculation date is inaccurate
Contraception during the rhythm period is not the most complete method of contraception, and many women cannot accurately calculate and avoid their ovulation period, resulting in unwanted pregnancies due to contraceptive failure. It is not possible to guarantee safe contraception alone, and it is necessary to avoid the actual ovulation period according to the perception of various physical and emotional changes.
3.Accurate algorithm for the contraceptive period
Measure whether the basal body temperature is about higher than before, whether the discharge is increased and clear like egg white, whether there is high energy and desire, whether there is a dull pain in the lower abdomen, a feeling of bloating, and whether there is ovulation bleeding that is different from menstruation? Only in this way can we understand and avoid the ovulation period in time to achieve the purpose of truly effective contraception.
Hello! The safe period is more accurate for women with regular menstruation, if menstruation is more regular, then, the fourteenth day before the next menstrual cramp is usually called ovulation day, plus the first five days and the last four days, a total of 10 days is called an ovulation period, that is, the danger period, in this time period is very likely to get pregnant. >>>More
The so-called safe period is 14 days before the day of your period, for example, if you come on the 30th, then push forward 14 days from the 30th, that is, the first few days before the 16th is your safe period.
It is the 7th day before menstruation to the 8th day after menstruation.
The safe period is relative, it is within 1-10 days after menstruation, and it is 1-12 days written in the book, so it is two days less for safety. It is only relative to the safe period from 22 days after menstruation to the day before menstruation.
Hello! If you have regular menstruation, the first 3 days and the last 4 days of your menstrual period are safe periods, but safe periods are not completely safe, and effective contraception is recommended.
