It is normal to bleed immediately after taking the emergency contraceptive pill because the emergency contraceptive pill contains progestin, and the dose of progestin is relatively large and can act on the thickened endometrium. Therefore, there may be symptoms of spotting or withdrawal bleeding within a week after taking the pill, but there will not be much bleeding, so you can use pads or no pads. Retreating bleeding does not mean that the contraception is successful. You should wait for more than 12 days after intercourse and use test strips or go directly to the hospital to take a blood test for HCG to rule it out. If there is a small amount of bleeding, you can observe it and pay attention to vulva hygiene, change underwear and wash vulva every day. If there is heavy bleeding, for example, 2 hours wet through a sanitary napkin, this is not normal, go to the hospital in time to stop bleeding treatment.
