"At present, many young women rely too much on emergency contraception, but the effect of emergency contraception is not as good as that of conventional contraception, and it also has a certain impact on menstruation. It can only be used as a remedy after contraceptive failure, but not as a routine contraceptive measure. " This is a hint given to women by Professor Fan Guangsheng, chairman of the Family Planning Branch of the Chinese Medical Association. At the same time, she pointed out that all women should choose the lowest effective dose of contraceptives.
The acceptance of oral contraceptives in China is relatively low. According to the statistics in 2004, only 65,438+0.69% women in China used oral contraceptives.
Professor Wu, a researcher at the Scientific Research Institute of the National Population and Family Planning Commission, pointed out that at present, China consumers' fear of oral contraceptives mainly stems from common misunderstandings, such as mistaken belief that oral contraceptives will increase weight and affect fertility. In fact, modern oral contraceptives are not the oral contraceptives of the past. Compared with other contraceptive methods, modern oral contraceptives will be more reliable if used correctly.
In addition to the reliability of contraception, contraceptives can also effectively regulate women's menstrual cycle, reduce the incidence of iron deficiency anemia, reduce the incidence of gynecological tumors (such as ovarian cancer and endometrial cancer), improve acne and prevent osteoporosis.
The estrogen content of modern oral contraceptives has dropped from 1960 150 micrograms to about 30 micrograms at present, which is safer. On the other hand, the China market is about to usher in the oral contraceptive Maxinle, whose estrogen content is only 20 micrograms. The content of estrogen in each pill is 10- 15 microgram lower than that of common oral contraceptives in the market at present, which can further reduce the side effects caused by estrogen.
Experts suggest that young women who take oral contraceptives for the first time can start with the lowest dose.
Side effects of birth control pills:
1. nausea: levonorgestrel, about 20%; Mifepristone, about 6%~7%. Nausea usually doesn't last more than 24 hours.
2. Vomiting: about 5% levonorgestrel; Mifepristone 1%.
3. Irregular uterine bleeding: Some women will have some drip bleeding after taking the medicine, and generally do not need treatment. The two are the same.
4. Menstrual changes: Some women have advanced or delayed menstruation. If menstruation is delayed for one week, urine pregnancy test should be done to determine whether emergency contraception has failed. The two are the same.
5. Others: breast pain, headache, dizziness, fatigue, etc. These symptoms are generally mild and last no more than 24 hours. The two are the same.
Precautions:
Any medicine has side effects. As the saying goes, there are three kinds of drugs, good and bad. Any drug should be analyzed from two aspects. The same is true of birth control pills, which are used by normal people. Drugs used in normal people must be very safe. Although these drugs are safe and effective, individual cases cannot be ruled out. It is common for many people to have stomach upset and nausea after taking it. Often this is the beginning, and it will get better in a month or two. If women take contraceptives for a long time, they should check whether they have this problem, gastrointestinal problems. Many people don't check up before taking birth control pills. If there are potential problems, taking contraceptives will show up. There may be other reasons. If the side effects disappear in a short time, don't worry too much.
Refer to other contraceptive methods:
1. IUD: A contraceptive device placed in a woman's uterine cavity. Long-term contraception can be achieved by placing it once, and fertility can be quickly restored after taking it out. Safe, effective, economical and does not affect sexual intercourse. "Release ring" is a medical operation in which a doctor puts an intrauterine device into the uterine cavity under aseptic conditions. As a foreign body, intrauterine device (IUD) makes a series of slight changes in the uterine environment, preventing the implantation and growth of fertilized eggs, thus achieving the purpose of contraception.
2. Subcutaneous implant: It is a safe and reliable long-acting contraceptive, which can be used for contraception for 5 years once implanted. Subcutaneous implantation is a contraceptive method. Under local anesthesia, a hose is implanted under the skin of the arm to slowly release synthetic progesterone. The side effect of subcutaneous implantation is menstrual disorder in some women.
3. Contraceptive needle: easy to use and high contraceptive efficiency. One injection can prevent pregnancy for 3 months, which is especially suitable for women who often forget to take medicine. Breast examination should be done regularly during use. If there is a lump, stop taking the medicine immediately. In addition, some users may have menstrual disorder, which is manifested by increased menstrual flow, prolonged menstrual period or a small amount of vaginal bleeding.
4. Oral contraceptives: contraceptive effect is achieved by inhibiting ovulation, and the incidence of side effects is extremely low. Even if used for a long time, it will not affect fertility. After stopping the drug, you can consider pregnancy without any adverse effects on your baby.
5. Sexual intercourse interruption: unable to control the outbreak and migration of sperm. The contraceptive safety factor of this method is less than 30%.
6. Safe period contraception: the success rate is 30%. Applicable people: Unless you are one of the few women whose metabolic system is as punctual as an alarm clock, don't take risks. In fact, for unmarried or newly married couples, using condoms is the best way, but many people think condoms are uncomfortable, and some people have nicknamed them' little raincoats'. In fact, after a few times, they get used to it.
