I took Yuting after having sex during ovulation.

The main purpose of female friends taking birth control pills is for contraception, but it does not mean that taking birth control pills at any time will be effective, because it is time-sensitive. It is easy to get pregnant by having sex after ovulation, and taking birth control pills for a long time is not good for the body. Therefore, if you do not want to get pregnant temporarily, you still have to choose a safe contraceptive method. So how long does it take for contraceptive pills to be effective after ovulation and sexual intercourse?

How long does the contraceptive pill last?

Within 72 hours after taking the medicine, if basic contraceptive measures are not taken or if you accidentally get pregnant, you should take the medicine within 72 hours (three days). The sooner you take the medicine, the better the effect. If it is still within 72 hours, it is recommended to take it as soon as possible. The contraceptive principle of Yuting is to prevent pregnancy by inhibiting uterine development, inhibiting or delaying ovulation, affecting uterine wall growth, affecting embryo implantation and other different stages. The embryo implants usually 3-4 days after fertilization. Therefore, more than 3 days later, the sperm and egg may have already implanted successfully, and Yuting will no longer serve as a contraceptive measure. Therefore, contraceptives such as Yuting must be taken within 72 hours, and the sooner they are taken, the higher the success rate.

Emergency contraception can slowly release estrogen and estrogens, thereby preventing the ovulation of the uterus and ovaries to achieve the purpose of contraception. Although it is a simple and convenient contraceptive measure, you should not rely on it too much, otherwise it will cause certain harm to the human body. All medicines are poisonous. Emergency contraception cannot be used indefinitely. Because emergency contraception affects the female hormones in the human body, experts remind female friends to enhance their awareness of prevention. Emergency contraception should not be used more than three times a year and can only be used once a month.

Taking too many contraceptive pills will have certain changes on the menstrual cycle, which may be advanced or delayed. Taking it multiple times will cause menstrual disorders and increased bleeding. The side effects of emergency contraception also depend on the individual's own conditions, mainly including nausea, stomach discomfort, headache, breast tenderness, slight weight gain, anxiety, depression, amenorrhea, chloasma and acne on the skin, etc. Once taken too much, the side effects will be more obvious. In addition, taking too much contraceptive measures can also lead to cancer, such as cervical cancer, liver cystadenoma, breast cancer, etc., so avoid taking too much emergency contraception.

How long after ovulation does it take for contraceptive pills to be effective?

The main ingredient of birth control pills is a lot of estrogen. Large doses of growth hormone can easily lead to endocrine disorders and changes in menstrual cycles in women. Therefore, long-term use is not recommended. It should only be taken once a month and no more than 3 times a year. Taking contraceptive pills is effective within 72 hours after sexual intercourse. If you have sexual intercourse again during the medication period, the time should be calculated again.

The ovulation period is when the probability of pregnancy is highest, and it can also be said to be the only chance of pregnancy, because women only have one ovulation opportunity in a month. Therefore, as long as both parties are healthy at this time, the sperm and egg can meet and combine normally, and can be transported to the uterus through the fallopian tubes for installation, and normal pregnancy can be achieved. In this way, it seems that pregnancy is a very simple and easy process, but the probability of pregnancy during ovulation is not 100%, and sometimes it is affected by many other factors.

The above is from the perspective of pregnancy, but from the perspective of contraception, the probability of pregnancy is relatively high at this time. Even if the man ejaculates outside the body, if there is no contraceptive method, the probability of pregnancy can still reach 60%. Therefore, it is necessary to take good contraceptive measures when having sex, take emergency contraception regularly, use condoms or reduce the frequency of sex.

The ovulation period is about 12-14 days before the next menarche. Generally, the possibility of pregnancy is very high if you have sex 4-5 days before and after the ovulation period. It is reasonable to take emergency contraception during ovulation.
