As a kind of emergency contraceptive, the main ingredient of the morning-after pill is a large amount of progesterone, which prevents women from ovulating normally and changes the level of uterine mucus in women’s bodies, making it difficult for sperms to enter and interfering with the combination of sperms and eggs and their implantation, so as to play the role of contraception.
Women need to be aware that although the morning-after pill can prevent pregnancy, it has more side effects. After taking the pill, the hormones in a woman’s body will start to be disorganized, and she may experience nausea, vomiting, headache and other reactions at the time of taking the pill, after which her menstrual cycle will start to be disorganized, which will also have an impact on her fertility in the future.
In addition, the success rate of the morning-after pill is not 100%, usually between 80% and 90%. Therefore, the morning-after pill should only be used as a temporary remedy and is not recommended for long-term use.
If you do not want to have children in the short term, it is recommended that you wear a condom or a contraceptive ring to prevent unwanted pregnancies from damaging your body.
