“Don’t, don’t do that, it’s not safe ……” I bet that most girls have said this at one time or another when they are having sex with their significant other. The young men and women who are “in love” will inevitably do some adult “things to do”, but if there are no safety measures in place, it can have very serious consequences. In order to help men and women in love to do “that thing” when they can be as safe as possible, some specialized production of gender products business can be a great deal of effort. But at some point, still can not avoid the “tragedy” occurred. Many gay men in order to pursue more “extreme” pleasure, did not hesitate to choose the “condomless entry”, but this practice for girls, is extremely irresponsible behavior. As adults, we all know that condoms are the first line of defense against pregnancy, and once you voluntarily give up wearing a condom, it means that the risk of unintended pregnancy for women is invariably greatly increased. And at this point, if you want to prevent pregnancy again, that leaves one method of contraception – the pill. As the saying goes, “It’s a drug that’s poisonous in three ways.” Since the pill is a drug, it will naturally have adverse effects on the body. If the quality of the pill you buy is not up to par, there may even be irreversible consequences! Therefore, before considering taking the pill, it is important to know in advance what are the common and “relatively safe” contraceptive pills and their harmful effects on a woman’s body. What are the most common types of birth control pills? There are three types of birth control pills commonly used in women’s daily lives: short-acting pills, long-acting pills, and emergency pills. The main ingredients of the short-acting pill are estrogen and progestin, the main ingredients of the long-acting pill are long-acting estrogen and progestin, and the main ingredients of the emergency contraceptive pill are highly effective and large amounts of progestin, and the difference in the main ingredients determines how much harm they do to girls. How do birth control pills work? Contraception is achieved by taking exogenous hormones that alter the concentration of vaginal and cervical mucus, change the way the fallopian tubes move, and prevent sperm from being transported. What harm can different birth control pills do to girls? 1, short-acting contraceptive pills: short-acting contraceptive pills due to less hormone content, after taking may appear mild swelling, fat phenomenon, is not conducive to girls to maintain the body, some girls will also exist dizziness, nausea, breast pain, mainly due to hormone stimulation and hormone levels caused by the endocrine disorder; 2, long-acting contraceptive pills: long-acting contraceptive pills drug hormone content is large, girls take, the drug The long-acting contraceptive pills will be stored in the fat interior, and then slowly released, girls taking long-acting contraceptives will also have the side effects of short-acting contraceptives, in addition to the possibility of increased leucorrhea, thinning, which can easily lead to vaginal inflammation, due to the continuous effect of drugs, girls may appear chloasma on the face, which has a certain adverse effect on the appearance of girls; 3, emergency contraceptives: emergency contraceptives contain a large number of highly effective 3, emergency contraceptive pills: emergency contraceptive pills contain a large number of highly effective progestin, will make the body hormone levels change dramatically, girls may appear nausea, vomiting, menstruation or even a short period of amenorrhea, some girls may appear persistent vaginal bleeding symptoms, frequent use of emergency contraceptive pills may also lead to premature ovarian failure of girls, liver damage and other performance, seriously harming the health of girls. When having sex, it is recommended to use external contraceptive measures, namely condoms, to reduce the number of times girls take the pill and minimize the harm it can do to girls.
