Patient's question:
I just finished my period... The next day, I had sex with my boyfriend. He came inside. Will I get pregnant??Doctor's answer:
Hello, it shouldn't be the case.A normally fertile woman menstruates once a month. The period from the start of one menstrual cycle to the first day of the next is called one menstrual cycle. If considering contraception, a woman's menstrual cycle can be divided into the menstrual period, ovulation period, and safe period. Safe period contraception is a method of abstaining from sexual activity during the ovulation period. This is a traditional contraception method, which was one of the commonly used methods for contraception both domestically and internationally before the advent of birth control pills and intrauterine devices.
A woman's ovulation date is generally about 14 days before her 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. Male sperm can maintain fertilizing ability in a woman's reproductive tract for 2-3 days, so sexual intercourse during the days before and after ovulation is more likely to result in pregnancy. For safety, we consider the 5 days before the ovulation date and the 4 days after it, including the ovulation date itself, as 10 days of the ovulation period. Because sexual intercourse during the ovulation period is more likely to result in pregnancy, this period is also known as the fertile period or the risky period.
The safe period is divided into the pre-ovulation safe period and the post-ovulation safe period. The period from the day the menstruation is clean to the day before the start of the ovulation period is the pre-ovulation safe period. The period from the day after the ovulation period ends to the day before the next menstrual period is the post-ovulation safe period. The post-ovulation safe period is safer than the pre-ovulation safe period. This is because some women may experience ovulation earlier due to environmental changes or emotional fluctuations, which shortens the pre-ovulation safe period, and they may not be aware of it. In such cases, the pre-ovulation safe period is not very safe. The ovary in one menstrual cycle
