Take Yutin for example, the 72-hour emergency contraceptive pill is 12.8 yuan, a total of 2 tablets, 1 tablet within 72 hours after intercourse, and then 1 tablet again in 12 hours, so that the full effect of contraception is achieved. Even though the contraceptive effect is very good, which can be as high as 98%, there are 2% of people who still have the possibility of pregnancy even though they take the emergency contraceptive pill orally within the prescribed time. In addition, because the side effects of the emergency contraceptive pill are relatively large, do not take it orally unless it is a last resort. It is best if you can use condoms for contraception, which basically has no side effects. If you don’t want to get pregnant for a long time, it is recommended that you go to the hospital 3-7 days after your period to get an intrauterine device, which is a reversible method of contraception, and if you want to plan a pregnancy, you can take the IUD out earlier.
