If you take the emergency contraceptive pill one month after abortion, it will cause the following effects clinically: 1. Because the emergency contraceptive pill is a highly effective progestin, it is likely to cause withdrawal bleeding from the endometrium after stopping the pill, and the vagina will show bleeding, which is often not much and will be clean on its own in 3-5 days. 2. The emergency contraceptive pill has the effect of suppressing ovulation, and suppressing ovulation from the ovary will make the normal physiological function be suppressed. It may cause irregular vaginal bleeding and temporary menstrual disorders, so it is recommended to do symptomatic treatment. It is recommended that if you can use condoms in your daily life, try to use them because they are safe and hygienic and have no side effects.
