Is it still useful to take emergency contraceptive pills if you have already ovulated?

If the woman's egg has already been discharged during intercourse, then taking birth control pills will still be effective after intercourse. This is because contraceptives can not only inhibit the discharge of eggs, but also affect the implantation of the embryo formed by the combination of sperm and egg. Mainly, contraceptives can change the natural environment of the uterine cavity, thereby achieving the purpose of contraception. Therefore, no matter whether a woman has ovulated or not, as long as she has sex without taking any contraceptive measures, taking birth control pills will have a certain contraceptive effect, but it just cannot be 100%.

There are many types of contraceptive pills, including high-efficiency estrogen and mifepristone. This kind of birth control pill has an impact on the menstrual period, so we still do not strongly recommend that a woman use birth control pills frequently, because after taking birth control pills, it will cause menstrual disorders for this woman. For example, if we take birth control pills before ovulation during menstruation, it may suppress ovulation. If we take birth control pills after ovulation, it may suppress the pregnancy mechanism and change some of the uterine wall, which makes it difficult for her to get pregnant, for example, it makes her uterine wall and our hormones out of sync.

Taking birth control pills after ovulation is still effective. This is because in addition to suppressing ovulation, birth control pills can change the compatibility of the uterine wall, causing the uterine wall to develop out of step with the embryo, and can inhibit the implantation of the embryo combined with the sperm and egg. Even though there is ovulation and fertilization has already occurred, when the sperm and egg combine and reach the uterus, the uterine wall at this time is different from usual, which can prevent the sperm and egg from combining and forming a bed inside.

Does taking one contraceptive pill actually work?

Some birth control pills only require one pill to achieve the actual contraceptive effect, while others require two pills. For example, Jin Yuting only requires one pill, and if taken orally within 72 hours after intercourse, it can achieve the actual contraceptive effect. You need to take two Yuting pills. The first one is to be taken orally within 72 hours after intercourse, and then take another one 12 hours later to achieve the actual contraceptive effect.

Unmarried pregnancy in women is often related to not wearing a condom during sexual intercourse or accidentally getting pregnant. Many couples let the woman take an emergency contraceptive pill before having sex, thinking that if the woman takes long-term contraceptive pills internally, they will not have to worry about anything. In fact, whether emergency contraception is effective has a lot to do with the actual situation between the couple. If the couple is together for a long time and insists on taking contraceptives every day, generally speaking, they can have a better contraceptive effect. But if the couple's sexual life is irregular, it is best to choose highly effective contraceptives.
