Which contraceptive pills work best

There are three common types of contraceptive pills: long-acting, short-acting and emergency contraceptive pills. Long-acting contraceptive pills are chosen to be taken orally on the fifth day of menstruation, with an additional pill taken on the 20th day of menstruation, and one pill taken orally on the fifth day of each subsequent menstruation to achieve the purpose of long-acting contraception, with the disadvantage of side effects such as thrombosis, pigmentation and body fat. The short-acting contraceptive pills often used are Mafulon, Eusemide, Eusyue, etc. The short-acting contraceptive pills have few side effects and a high contraceptive rate. Emergency contraceptive pills are Yutin and Mifepristone tablets which are both commonly used for emergency contraception and are effective but have a 4% contraceptive failure rate. Therefore, Mafolone, Ursine, Ursine, Yutin, and Mifepristone tablets are all drugs that can be used for contraception.
