How to take birth control pills to prevent pregnancy

There are two kinds of contraceptive pills, one is a 24-hour contraceptive pill, and the other is a 72-hour contraceptive pill. Therefore, the effectiveness of these two contraceptive pills is different, and the effectiveness of the contraceptive pills is also related to one's physical condition. So how long is the right time to take birth control pills, and how can we consider the birth control measures to be successful after taking birth control pills?

How long is it reasonable to take birth control pills

Most contraceptive pills are taken orally, and as for the question of when is the best time to take contraceptive pills, the principle of contraceptive pills is to inhibit ovulation and change cervical mucus, making it difficult for sperm to implant in the embryo and achieve the purpose of contraception. Therefore, in order for emergency contraception to play a greater contraceptive effect, it is necessary to choose the appropriate time of administration according to the characteristics of different emergency contraceptives.

Birth control pills are a type of medicine that acts as a contraceptive during sexual intercourse. The first pill can be taken within three days of sexual intercourse, and the second pill can be taken half a day later. The sooner you take it, the better the effect. The main ingredient of the contraceptive pill is estrogen. The basic principle of the drug's efficacy is basically the same as that of short-term contraceptives and is suitable for women under 40 years old.

Short-term contraceptives are taken from the fifth day after menarche. The way to take short-term contraceptives is to take one pill a day for twenty-two days, which can provide contraceptive measures for one month. The main function of short-term contraceptives is to inhibit ovulation and prevent the normal growth of the uterine wall. It is suitable for women without underlying diseases or diabetes.

Generally, taking one tablet on the fifth day after menarche and another tablet 20 days later can achieve effective contraceptive effects. Long-term contraceptives mainly contain artificial estrogen and high-efficiency estrogen, which can inhibit ovulation and play a long-term contraceptive role. It is suitable for women who cannot have an IUD and are unwilling to use other contraceptive methods.

When is the best time to take emergency contraception depends not only on the type of emergency contraception but also on the woman's personal situation. However, general emergency contraception comes with additional instructions. If you are not sure when to take it, you can read the article in detail or consult a doctor. If your period is delayed for too long after taking emergency contraception, you should check whether you are accidentally pregnant.

How to determine whether contraceptive measures are successful after taking birth control pills

Taking birth control pills within 72 hours after intercourse can have a contraceptive effect. The sooner you take it, the better the effect. If withdrawal bleeding occurs after intercourse and the amount of withdrawal bleeding is large, it can be regarded as a menarche, indicating that the contraceptive measure is successful.

First of all, pay attention to the time of taking oral contraceptives: it is within seventy-two hours after intercourse. If it is taken within this time range, it is within the effective period. But please note that the contraceptive effect rate of birth control pills cannot be 100%. Also, please note that oral contraceptives will delay normal menstruation, so pay attention to observe. If the normal menstruation is delayed by no more than one week, it means that the contraceptive measures are successful.

Generally speaking, taking birth control pills within 72 hours after unprotected sexual intercourse is an effective contraceptive measure. Some people may experience withdrawal bleeding after taking the drug, while others may not. Contraceptive pills can easily cause disruptions to your menstrual cycle. The next menstrual period may be advanced or delayed. It is recommended that you avoid taking contraceptive pills as much as possible.

Generally, if you take birth control pills before your period, a small number of women may experience withdrawal bleeding. If the duration and bleeding are similar to normal periods, you should not get pregnant. Then your next menstrual period will be calculated from the beginning of your withdrawal bleeding. There are also birth control pills that only need to be taken three times a year, only once in a menstrual cycle, and there are also birth control pills that only work for one-time daily life.
