Emergency contraceptive pills can have an effect on your body if you take them 2 times in a week. The emergency contraceptive pill is taken within 72 hours after sex. By taking the emergency contraceptive pill, you can reduce the risk of unwanted pregnancy and achieve the purpose of contraception. However, if you take too much of the pill, it will affect the hormone level of women, which will lead to menstrual disorders, causing longer and more frequent menstruation, and irregular menstruation. In addition, if the emergency contraceptive pill is taken repeatedly, it may interfere with the fertilization of the egg and increase the risk of ectopic pregnancy if the pregnancy is still unwanted in the middle of the pill. Therefore, the best method of contraception is to use condoms or birth control rings instead of the regular use of emergency contraceptives.
