I had my period for a month and half now after surgery ectopic pregnancy have also checked but the result is negative why?

Possible explanations for continued bleeding after surgery for ectopic pregnancy:

1. Retained Products of Conception: It's possible that some pregnancy tissue was left behind after the surgery, which can cause ongoing bleeding. This residual tissue may need to be removed to stop the bleeding.

2. Hormonal Imbalances: Ectopic pregnancy and the surgery can disrupt the hormonal balance in the body, leading to irregular or prolonged bleeding. The hormonal levels usually stabilize over time, but it may take several weeks or even months for the bleeding to stop completely.

3. Infections: Infection at the surgical site or in the uterus can also cause bleeding. Symptoms of infection may include fever, abdominal pain, and foul-smelling discharge. Antibiotics or other treatments may be needed to clear the infection and stop the bleeding.

4. Underlying Medical Conditions: Certain medical conditions, such as thyroid disorders, uterine fibroids, or clotting disorders, can cause abnormal bleeding. These conditions should be evaluated and managed to address the bleeding.

Since you've had persistent bleeding for an extended period, it's important to see a healthcare provider again for a thorough evaluation. The doctor may perform additional tests, such as an ultrasound or blood work, to determine the cause of the bleeding and provide appropriate treatment. Don't hesitate to seek medical attention if you have any concerns about your health or the ongoing bleeding.
