Bleeding after taking Plan B is a common and generally normal side effect. Plan B contains the hormone levonorgestrel, which can cause hormonal changes that affect the lining of the womb, leading to spotting or light bleeding shortly after taking the pill. This bleeding is not the same as a period and can vary in intensity and duration, typically lasting a few days but sometimes up to a week. Plan B can also cause changes in the timing and flow of the next menstrual period, making it come earlier, later, lighter, or heavier than usual. However, if the bleeding is very heavy (soaking through pads or tampons quickly), lasts longer than a week, or is accompanied by severe pain or other concerning symptoms, it is important to seek medical advice. Additionally, if your period is more than a week late after taking Plan B, taking a pregnancy test is recommended to rule out pregnancy. In summary, bleeding after taking Plan B is usually a harmless effect of the hormonal changes caused by the pill, but monitoring the amount and duration of bleeding and any other symptoms is important to ensure there are no complications.
