Is the 4th day after menstruation the dangerous period?

For men and women who do not want to have children after having sexual relations, it is urgent to take safety measures. The 4 days after menstruation is a dangerous period. According to the algorithm of the safe period, the first eight days and the last seven days are not considered a safe period, and the 4 days are included in this period. If you don't plan to have children, it is best to take safe contraceptive measures, so it is important to avoid this dangerous period. Of course, the man can also choose to wear a condom.

A woman's ovulation date is generally about 14 days before the next menstrual period. After the egg is released from the ovary, it can survive in the fallopian tube for 1-2 days, waiting for fertilization; the male's sperm can maintain its fertilization ability in the female's reproductive tract for 2-3 days, so it is easy to get pregnant through sexual intercourse a few days before and after the egg is released. To be on the safe side, we call the 5 days before and 4 days after ovulation, together with the ovulation day, a total of 10 days, the ovulation period. Because it is easy to get pregnant through sexual intercourse during the ovulation period, the ovulation period is also called the fertile period or the dangerous period.

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 the ovulation, so before the safe period ovulation will be shortened, but did not know their own, so before the safety period ovulation is not safe. The opportunity that the ovary has row two eggs in a menstrual cycle is very rare, that is, after ovulation to the next menstrual cramps before this period of time usually won't happen again the second time of ovulation, so the safety period after ovulation is relatively safe.

The key to using safe period contraception is to determine the female ovulation date. There is generally no special feeling when ovulation occurs, even though some women may have symptoms such as lower abdominal pain, back pain, breast swelling and mood changes, but these phenomena are not specific symptoms of ovulation and therefore cannot be used as a basis for ovulation. Menstruation and ovulation change cyclically, and there is a close relationship between the two. If you understand the changing patterns of the two, you can determine the ovulation date through indirect methods. There are many ways to determine the ovulation date, and the methods that women can master themselves include: calculating based on the menstrual cycle, measuring basal body temperature, and observing cervical mucus secretion.
