Irregular menstrual cycle

I haven't had my period for six months.
On April 30, I went to a gynecology clinic for a check-up.
They performed a urine test and an ultrasound, which showed that I was not pregnant.
The doctor prescribed me two different medications to take for three days, one pill of each.
After finishing the medication, I waited for seven days, but my period still hadn't come.
On May 7, which was the seventh day, I visited another gynecology clinic.
They also conducted a urine test, confirmed that I was not pregnant, and prescribed me medication to take for five days.
After seeing the doctor, I took the first pill in the morning, and by noon, I noticed a little bit of bleeding.
I thought my period had started, so I didn't take the medication anymore.
However, by the evening, the bleeding had stopped completely, and there was no discharge at all.
What does this mean?

Hello: The menstrual cycle is initiated by the secretion of gonadotropin-releasing hormone (GnRH) from the hypothalamus.
If this hormone is suppressed and not secreted, it can result in a situation like yours, where menstruation has not occurred for six months.
In this case, there is no follicular development and no estrogen secretion, so the endometrial cells do not proliferate.
Even with the administration of progesterone to induce menstruation, it will not occur.
If you were previously taking medication that contained estrogen, the endometrium would have experienced some degree of proliferation, which is why there may be slight bleeding after stopping the medication.
However, since the amount of estrogen taken was insufficient, only a small amount of bleeding occurs.
Thank you for your message!

More Info

Irregular menstrual cycles can be a source of concern for many women, and understanding the underlying causes and treatment options is crucial for managing this condition effectively. Based on your description, it appears that you have experienced a significant disruption in your menstrual cycle, with a six-month absence of menstruation (amenorrhea) followed by some irregular bleeding after starting medication.

Causes of Irregular Periods
Irregular periods can be caused by a variety of factors, including hormonal imbalances, stress, significant weight changes, medical conditions, and lifestyle factors. Here are some common causes:
1. Hormonal Imbalances: The menstrual cycle is regulated by hormones such as estrogen and progesterone. Conditions like polycystic ovary syndrome (PCOS), thyroid disorders, and hyperprolactinemia can lead to irregularities.

2. Stress and Lifestyle Changes: Emotional stress, significant life changes, or even changes in your daily routine can affect your menstrual cycle. Stress can lead to hormonal fluctuations that disrupt the regularity of your periods.

3. Weight Fluctuations: Both weight gain and weight loss can impact your menstrual cycle. Being underweight or overweight can lead to hormonal imbalances that affect ovulation and menstruation.

4. Medical Conditions: Conditions such as endometriosis, uterine fibroids, or pelvic inflammatory disease can also cause irregular bleeding and changes in menstrual patterns.

5. Medications: Certain medications, including hormonal contraceptives, can affect your menstrual cycle. If you have recently started or changed medications, this could be a contributing factor.

Treatment Options
The treatment for irregular periods depends on the underlying cause. Here are some common approaches:
1. Hormonal Therapy: If hormonal imbalances are identified, doctors may prescribe hormonal treatments such as birth control pills or hormone replacement therapy to help regulate your cycle.

2. Lifestyle Modifications: Addressing lifestyle factors such as stress management, maintaining a healthy weight, and regular exercise can help restore normal menstrual function.

3. Medications: In cases where medications are causing irregularities, your doctor may adjust your prescriptions or suggest alternatives.

4. Monitoring and Follow-Up: Regular follow-up appointments with your healthcare provider are essential to monitor your menstrual cycle and make necessary adjustments to your treatment plan.

5. Diagnostic Procedures: If irregularities persist, further diagnostic procedures such as blood tests to check hormone levels, pelvic ultrasounds, or endometrial biopsies may be necessary to rule out underlying conditions.

Your Situation
In your case, it seems that after a prolonged absence of menstruation, you experienced some bleeding after starting medication, which can be a common response as your body attempts to regulate itself. The initial bleeding you observed could be a breakthrough bleed, which is not uncommon when starting hormonal treatments. However, since the bleeding stopped and you are experiencing uncertainty about your cycle, it is essential to follow up with your healthcare provider.

If you have not had a regular period for six months, and the bleeding you experienced was minimal and not sustained, it would be advisable to continue monitoring your symptoms and maintain open communication with your doctor. They may recommend continuing the medication or exploring other treatment options based on your response.

Conclusion
Irregular periods can be distressing, but understanding the potential causes and treatment options can empower you to take control of your reproductive health. It is crucial to work closely with your healthcare provider to identify the underlying issues and develop a personalized treatment plan that addresses your specific needs. If you have further concerns or if your symptoms persist, do not hesitate to seek additional medical advice.
