1, long-term contraceptive type
The so-called long-acting contraceptive, its medical name is short-acting oral contraceptive. Long-acting (short-acting) contraceptives include Mindikang, Mafulong and Tejule, which means you must take them every day and for a long time. Each pill can only be taken for one day. Progesterone is really used for contraception.
Long-acting contraceptives include long-acting contraceptives in addition to common long-acting short-acting oral contraceptives. Long-term long-acting contraceptives only need to be taken twice a month. But please think about it in a stupid way: if long-term short-acting oral contraceptives are equivalent to drinking two liters of water a day, then long-term long-acting contraceptives are equivalent to drinking only 30 liters of water twice a month.
Long-term short-acting oral contraceptives (MindingCouple, Marvelon, Tejule) contain progesterone and a small amount of estrogen. Among them, progesterone reduces the secretion of GnRH in human hypothalamus through negative feedback, thus reducing the secretion of FSH and LH, thus making it difficult for follicles in women to grow and ovulate, thus inhibiting ovulation and inhibiting the ability of women to produce progesterone and estrogen themselves. By inhibiting ovulation, its contraceptive efficiency is almost 100%. By reducing the progesterone and estrogen secreted by women themselves, the progesterone and estrogen contained in long-term short-acting oral contraceptives replace the progesterone and estrogen secreted by women themselves. In the case of taking short-acting oral contraceptives for a long time, women will only have luteal phase and menstrual period, and ovulation period will be cancelled.
In fact, progesterone alone can achieve the purpose of contraception. The reason why long-term short-acting oral contraceptives contain a small amount of estrogen besides progesterone is to prevent the estrogen level of women from falling too much.
Because the contraceptive mechanism of long-term short-acting oral contraceptives is to inhibit ovulation, and as long as there are no eggs, fertilized eggs will not form, so long-term short-acting oral contraceptives can effectively avoid ectopic pregnancy and prevent ovarian cancer to some extent.
2. Effect on menstruation
After taking emergency contraceptives, the menstrual period will generally be postponed, and the number of days delayed will vary from person to person. Some people eat it once every once in a while, but some people can cause menopause for 2 or 3 months, which is very worrying. Because you are worried about pregnancy, you should observe at any time to avoid pregnancy, and taking emergency contraceptives is easy to cause ectopic pregnancy. Be cautious in this regard. Once pregnancy symptoms appear, you should go to the hospital without hesitation.

3. Contraceptive advice
Taking emergency contraception is a very easy contraceptive method, but it is only effective if women of childbearing age take it within 72 hours after contraceptive failure. Because the main components of emergency contraceptives are estrogen and progesterone, if they are taken for a long time or too many times, they will have great side effects. Therefore, it is recommended that female friends use contraceptives as little as possible for contraception. If you are worried that wearing condoms will affect the fun of sex life, you can choose ultra-thin double slip condoms, which are ultra-thin and can experience the same feeling as not wearing condoms.
Generally speaking, most women will have delayed menstruation after taking emergency contraception, but some women will have symptoms of early menstruation after taking emergency contraception, which is mainly due to the temporary increase of hormone levels in women's blood after taking emergency contraception, and withdrawal bleeding will occur when hormone levels drop, mainly due to early menstruation. This is a manifestation of the side effects of emergency contraception, and menstruation generally returns to normal in about 1-3 menstrual cycles.
However, whether menstruation is delayed or advanced, everyone's situation is different. Of course, some women may have amenorrhea after taking emergency contraception, which is also very common in clinic. Contraceptive pills are harmful to health, so it is safer and more effective to consider choosing condoms for contraception for those who need contraception.
