Patient's question:
I had my period on November 27 and it stopped on December 2. On December 10, I had sexual intercourse with my husband. On December 12, I took two Minton pills. Then, on the morning of December 18, I had my period again, and it ended on December 22. How should I calculate my safe period this month? Is the period after January 13 safe?Doctor's answer:
Hello, every woman's safe period is different.Safe period refers to the normal menstrual cycle, approximately 28 days per cycle. Ovulation occurs around the 14th day after menstruation. If the released egg is not fertilized, it can only survive for about two days. Sperm deposited into the vagina during sexual intercourse can also survive for about four days. Therefore, it can be inferred that if there is no sexual activity four days before and four days after ovulation, pregnancy will not occur. Thus, if this method is used, couples can only avoid sexual activity during menstruation, four to six days after menstruation, and ten days before menstruation to prevent pregnancy. Therefore, if this method is used, couples can only engage in sexual activity during menstruation, four to six days after menstruation, and ten days before menstruation. This period is considered the "safe period." This is the only contraception method permitted by God. However, since every woman's menstrual cycle duration varies, the effectiveness of this method is not always ideal. There are three methods to calculate the safe period:
1. Calendar method: When deciding to use this method for contraception, you must first record the duration of your menstrual periods for six consecutive months. Then, calculate the number of days of ovulation each time to determine your safe period. When recording six menstrual periods, subtract three days from the shortest ovulation day and add three days to the longest ovulation day. This period is considered the possible fertile days, so sexual activity should be avoided.
2. Basal body temperature method: This is a relatively accurate way to determine the day of ovulation. It is based on the principle that basal body temperature slightly increases during ovulation. This method is adopted because...
