If a normal woman mistakenly takes the emergency contraceptive pill, it will cause the following clinical side effects: first, the emergency contraceptive pill, because it is a high potency progestin, so after stopping the pill, it will be about 3-5 days after the vaginal bleeding, the bleeding is not much, but it lasts about 3 days before it clears up, and some may have vaginal bleeding for more than a week, and need to be given the appropriate treatment. Secondly, because emergency contraceptive pills contain highly effective progesterone, which is more than five times higher than the progesterone of other contraceptive pills, it can cause more serious consequences in the clinic. Once the body is more sensitive, it may affect the liver and kidney functions, so if the emergency contraceptive pill is mistakenly taken, it may cause the above side effects.
