Wearing a condom during lovemaking may be uncomfortable, affect the real experience, and may even spoil the atmosphere of passion at the critical moment. Therefore, many people will take a chance: there is a safe period, it is possible to not wear a condom, right? What is the safe period? The safety period can be divided into the pre-ovulatory safety period and the post-ovulatory safety period. Pre-ovulatory safety period refers to the period from the end of menstruation to the first 3 days of ovulation, while post-ovulatory safety period refers to the period from the end of ovulation to the next menstrual period. The post-ovulatory safety period is the period from the end of ovulation to the next menstrual period. The ovulation period is the period from 5 days before to 4 days after ovulation. For women with regular menstrual cycles, the day of ovulation is the 14th day before the next menstrual period. For example, if a woman with a regular menstrual cycle has her period on March 23. Then, the day of ovulation is March 9, and the ovulation period is from March 4 to March 13. The pre-ovulatory safety period is from the last clean period to March 1; the post-ovulatory safety period is from March 14 to March 22. Once the safety period is understood, here’s the question! Is the safe period really safe? Theoretically speaking, the time outside of ovulation and menstruation, when there are basically no mature follicles, is considered safe. The longer the time between ovulation and the period, the higher the safety factor. For example, the week before and after menstruation is relatively safe, and for women with regular menstrual cycles, ovulation and the safety period are also more regular, so you can master your own safety period to prevent pregnancy. However, the safety period is only a relative concept. Ovulation can sometimes be affected by factors such as diet, environment, hormone levels, and sexual stimulation, making ovulation occur earlier or later. Especially for women with irregular menstrual cycles and women who use sex hormone drugs, ovulation may also occur during the safety period, so the safety period is not always reliable and the safety period is not always safe. Can I go without a condom during the safe period? The doctor has something to say If you don’t have a plan to prepare for pregnancy, even if you are in the safe period, it is still more reliable to wear a condom, and if necessary, you still need to combine it with other scientific contraceptive methods, such as taking birth control pills. Many people who use the safe period to prevent pregnancy end up getting pregnant unexpectedly because of abnormalities in their ovulation and menstrual cycles. Especially for women with irregular menstrual cycles, contraception through the safe period often fails. Therefore, if you do not intend to get pregnant, you need to take effective contraceptive measures at any time to prevent unwanted pregnancy from causing unnecessary harm to your body.
