What causes bleeding 7 days after taking emergency contraceptive pills?

Generally, bleeding seven days after taking emergency contraceptive pills may be caused by withdrawal bleeding, menstrual onset, drug side effects, cervicitis, endometrial polyps, etc. Patients should promptly visit a正规 hospital for diagnosis and appropriate treatment based on the specific condition. Detailed analysis is as follows:

1. Withdrawal Bleeding

After taking emergency contraceptive pills, some patients experience elevated hormone levels in the body. When the endometrium loses hormonal support, it may shed, resulting in withdrawal bleeding. This is a normal physiological response that usually does not require special treatment—close observation is sufficient.

2. Menstrual Onset

Bleeding seven days after taking emergency contraception could also be due to the onset of menstruation, caused by endometrial shedding. This is considered normal. It is recommended that patients rest adequately, maintain warmth to avoid chilling, and avoid raw, cold, spicy, or irritating foods.

3. Drug Side Effects

Some patients may experience menstrual disorders after taking emergency contraceptive pills, including early or delayed periods and irregular vaginal bleeding. Therefore, the aforementioned symptoms might be side effects of the medication. If the bleeding is light, special treatment is generally not required.

4. Cervicitis

Bacterial infection in the cervix may cause congestion of cervical mucosa, leading to symptoms such as vaginal bleeding, abdominal pain, and abnormal discharge. Under medical guidance, patients can take medications such as Fuke Qianjin Tablets, Kangongyan Tablets, or Kangfuyan Capsules to alleviate symptoms.

5. Endometrial Polyps

If the endometrium is continuously irritated by inflammation, excessive proliferation during the menstrual cycle may lead to endometrial polyps, causing vaginal bleeding. Some patients may also experience increased discharge or abdominal protrusion. Treatment typically requires visiting a正规 hospital for procedures such as polyp removal, hysteroscopic surgery, or hysterectomy. Additionally, proper postoperative care is essential.

In addition to the above, endometritis could also be a possible cause. Patients are advised to seek timely medical attention to determine the exact cause and prevent disease progression.
