Is it normal to have my period 19 days after surgery for a chocolate cyst?


Hello, doctor.
I would like to ask about my situation.
I underwent laparoscopic surgery for an endometrioma on April 8th, and I started taking Dienogest on April 15th, one tablet daily.
The doctor informed me that my menstrual period might be delayed for two to three months and that mild bleeding could be a side effect.
However, my period unexpectedly started on April 27th! The blood was bright red, and there were even blood clots, with a significant amount that a panty liner couldn't contain.
I only feel some lower back discomfort, but is this normal? I haven't had time for a follow-up appointment recently, so I hope there isn't an issue with the surgical site.
The external surgical wound is healing well, but I'm more concerned that the sudden onset of my period might indicate a problem with an internal injury.

Dear A-Zhen, thank you for your question.
After undergoing ovarian surgery, hormonal changes may occur, which can lead to abnormal uterine bleeding.
Generally, unless the bleeding is heavy, it is recommended to observe for one to two menstrual cycles.
As for the internal wounds, an examination is necessary to assess the situation.
Thank you for your inquiry!

More Info


It is understandable to have concerns about your menstrual cycle following laparoscopic surgery for a chocolate cyst (endometrioma). The situation you described, where you experienced your period 19 days post-surgery, can be quite common and is influenced by several factors.

First, it's important to recognize that hormonal fluctuations are expected after any surgical procedure, especially one involving the reproductive organs. The surgery itself can disrupt the normal hormonal balance, which may lead to unexpected menstrual patterns. In your case, the fact that you started taking medication (likely a hormonal treatment) shortly after surgery may also contribute to changes in your menstrual cycle. The medication you mentioned, likely a form of hormonal therapy, is intended to manage endometriosis symptoms and can sometimes cause irregular bleeding or changes in the menstrual cycle.

The timing of your period, just 19 days after surgery, could be attributed to the body's response to the surgical intervention and the hormonal changes induced by the medication. While your doctor initially indicated that your period might be delayed for two to three months, individual responses can vary significantly. Some women may experience an earlier return to menstruation, especially if their body is adjusting to the hormonal changes.

Regarding the characteristics of your menstrual flow—bright red blood and the presence of clots—this can also be a normal response post-surgery. After surgery, the endometrial lining may shed more vigorously, leading to heavier bleeding and the formation of clots. However, if the bleeding is excessively heavy (soaking through pads in an hour or less) or accompanied by severe pain, it would be advisable to seek medical attention.

Your concern about internal wounds is valid, but since you mentioned that your surgical site is healing well and you are only experiencing mild discomfort, it is less likely that there is a significant issue. However, if you notice any unusual symptoms, such as severe pain, fever, or foul-smelling discharge, you should contact your healthcare provider immediately.

In terms of managing your recovery, it is essential to follow your doctor's advice regarding activity levels and follow-up appointments. If you are unable to return for a check-up, consider reaching out to your healthcare provider via phone or telemedicine to discuss your symptoms and any concerns you may have.

Lastly, it is crucial to monitor your menstrual cycle over the next few months. If your periods remain irregular or if you experience significant changes in your symptoms, a follow-up appointment may be necessary to reassess your treatment plan and ensure that everything is healing appropriately.

In summary, while it is not uncommon to experience your period shortly after surgery for a chocolate cyst, it is essential to remain vigilant about your symptoms and maintain open communication with your healthcare provider. Your body is undergoing significant changes, and understanding these changes can help you manage your recovery effectively.
