Menstrual regulation medications, menstrual issues, ovarian cysts?

Hello doctor, I took medication to delay my menstrual period in February due to traveling.
I started taking it on June 2nd, and my period came the day after taking it for one day.
However, I continued taking the medication for two more days until August 2nd.
As a result, my menstrual period lasted four days longer than usual.
In March, I did not have a period, but in April, it started on the 18th and lasted until the 28th, with a heavier flow than usual, lasting 5-6 days longer.
A week after my period (early May), I experienced a small amount of brown discharge with some blood, which lasted for three days.
I still have not had a period since then.
Recently, I had an ultrasound examination, which revealed a cyst on my right ovary measuring approximately 2.8 cm.
However, the doctor is uncertain whether it is benign or malignant and advised to follow up after my period.
I would like to ask the following questions: 1.
Is the irregularity in my menstrual cycle due to the medication or the cyst? 2.
What methods can be used to quickly determine whether the cyst is benign or malignant?

Understanding menstrual irregularities and ovarian cysts can be complex, especially when considering factors such as hormonal treatments and underlying conditions. Based on your situation, let's delve into your questions regarding the irregularities in your menstrual cycle and the ovarian cyst discovered during your ultrasound.

1. Menstrual Irregularities: Causes and Effects
Your menstrual cycle can be influenced by a variety of factors, including hormonal medications, stress, lifestyle changes, and underlying health conditions such as polycystic ovary syndrome (PCOS). In your case, taking medication to delay your period could have disrupted your hormonal balance, leading to the irregularities you are experiencing. The fact that your period lasted longer than usual and was heavier than normal could be a direct result of the hormonal changes induced by the medication. Additionally, the presence of an ovarian cyst can also contribute to menstrual irregularities. Ovarian cysts can affect hormone levels and may lead to changes in the menstrual cycle, including delayed periods or abnormal bleeding.

2. Determining the Nature of the Ovarian Cyst
To ascertain whether the cyst is benign or malignant, several approaches can be taken. Initially, your healthcare provider may recommend monitoring the cyst through follow-up ultrasounds. Benign cysts, such as functional cysts, often resolve on their own within a few menstrual cycles. If the cyst persists or grows, further evaluation may be necessary.
A few diagnostic methods can help determine the nature of the cyst:
- CA-125 Blood Test: This test measures the level of a protein that is often elevated in women with ovarian cancer. However, it is important to note that elevated CA-125 levels can also occur in benign conditions, so it is not definitive on its own.

- MRI or CT Scan: These imaging techniques can provide more detailed information about the cyst's characteristics and help differentiate between benign and malignant lesions.

- Laparoscopy: In some cases, a minimally invasive surgical procedure may be performed to directly visualize the cyst and take a biopsy if necessary. This is often considered if there are concerning features on imaging studies or if the cyst does not resolve over time.

In summary, while the hormonal medication you took may have contributed to your menstrual irregularities, the ovarian cyst could also be a significant factor. It is essential to follow up with your healthcare provider for further evaluation and monitoring of the cyst. Regular check-ups and imaging studies will help ensure that any changes in the cyst's characteristics are promptly addressed. If you experience any new symptoms, such as severe pain, fever, or significant changes in bleeding patterns, it is crucial to seek medical attention immediately.
Understanding the interplay between hormonal treatments, ovarian cysts, and menstrual irregularities is vital for managing your reproductive health effectively. Always consult with your healthcare provider for personalized advice and treatment options tailored to your specific situation.
