Menstrual Irregularities: Causes and Treatments Explained

I'm sorry

Hello: Due to the absence of my menstrual cycle in March and April, I visited the obstetrics and gynecology department on May 3.
After a pregnancy test, it was confirmed that I was not pregnant, and I received an injection.
The doctor mentioned that this injection is a menstrual induction shot when there is no pregnancy, but if pregnancy occurs after the injection, it becomes a pregnancy maintenance shot.
My first question is, does such an injection really exist? After the injection, my period started on May 10, with a light flow, bright red color, no menstrual cramps, and lasted for about 7 days, requiring a panty liner by the third day.
However, on May 23, I experienced bleeding again, which was slightly heavier than on May 10, but still manageable, with a darker color and no menstrual cramps.
Today is May 25, and the bleeding has not yet stopped.
My second question is, why did this happen again? Is there something wrong with my body? Thank you!

1.
The commonly used menstrual induction injection is a progesterone preparation, which can also be used as a hormone for early pregnancy support.

2.
After receiving the menstrual induction injection, menstruation may occur, and bleeding may happen again half a month later, which could be ovulation bleeding.
Some women may experience this normal phenomenon, usually resolving within a few days.
If there are any concerns, it is advisable to consult a gynecologist.

More Info

Menstrual irregularities can be concerning and may arise from various underlying causes. Based on your description, it seems you have experienced a delay in your menstrual cycle followed by two episodes of bleeding within a short period. Let's break down your concerns and provide some clarity on the situation.

Understanding the Injection
Firstly, regarding the injection you received, it sounds like you were given a medication commonly referred to as a "progestin" or "progestogen." These injections can be used to induce menstruation in women who have missed their periods, especially when pregnancy has been ruled out. The mechanism of action involves the regulation of hormonal levels, particularly progesterone, which plays a crucial role in the menstrual cycle.
In some cases, if a woman were to become pregnant after receiving this injection, it could indeed have a role in supporting the pregnancy, hence the dual purpose you mentioned. However, it is essential to note that such injections should be administered under strict medical supervision, and the potential for unintended pregnancy should always be discussed with your healthcare provider.

Analyzing Your Bleeding Episodes
Now, regarding your menstrual bleeding:
1. First Episode (May 10): The onset of your period following the injection, characterized by light flow and bright red color, is consistent with a normal menstrual cycle. The absence of menstrual cramps is also not unusual, as some women experience varying degrees of discomfort during their periods.

2. Second Episode (May 23): The subsequent bleeding you experienced, which was heavier and darker in color, could be attributed to several factors. It is not uncommon for women to experience "breakthrough bleeding" after hormonal treatments, especially if the body is adjusting to the changes in hormone levels. This type of bleeding can occur between periods and may vary in volume and color.

3. Ongoing Bleeding (as of May 25): If the bleeding has not stopped, it is essential to monitor the situation closely. Prolonged bleeding can be a sign of several conditions, including hormonal imbalances, uterine fibroids, polyps, or other underlying issues that may require further evaluation.

Recommendations
Given your situation, here are some recommendations:
- Consult Your Healthcare Provider: It is crucial to follow up with your gynecologist or healthcare provider, especially since you are experiencing ongoing bleeding. They may perform a pelvic examination, ultrasound, or other diagnostic tests to determine the cause of your symptoms.

- Track Your Symptoms: Keep a record of your menstrual cycles, including the dates, duration, flow intensity, and any associated symptoms (like pain or discomfort). This information can be invaluable for your healthcare provider in diagnosing any potential issues.

- Consider Lifestyle Factors: Stress, significant weight changes, excessive exercise, or changes in diet can also impact menstrual regularity. Reflecting on any recent lifestyle changes may provide additional context for your symptoms.

- Be Aware of Warning Signs: If you experience severe pain, heavy bleeding (soaking through a pad or tampon every hour), or any other concerning symptoms, seek medical attention promptly.

In conclusion, while hormonal treatments can effectively regulate menstrual cycles, they can also lead to temporary irregularities as your body adjusts. Continuous communication with your healthcare provider is essential for managing your menstrual health and addressing any concerns that arise.
