Does Menstrual Induction Injection Affect Your Period and Flow? - Obstetrics and Gynecology

Will receiving a menstrual induction injection affect subsequent menstrual cycles and bleeding volume?


On June 2nd, I received an injection to induce menstruation due to a delayed period (the endometrium was thickened).
However, two days after the injection, I caught a severe cold with a fever and went to the hospital for IV fluids and antipyretics.
On June 5th, I had some menstrual bleeding, which was light, and by June 8th, I passed a blood clot, after which the bleeding stopped.
I calculated that my period should be due this month, but for the past three days, I've only had spotting.
If I get enough rest, there is no bleeding.
Could this be a result of the injection I received to induce menstruation?

Hello, based on your description, it seems that you may be experiencing hormonal imbalance and irregular menstrual cycles.
Generally, menstrual induction injections are not likely to cause this.
It is recommended that if your menstrual period does not arrive after one week, you should consult a gynecologist for an examination.
Thank you! Wishing you peace and health, Dr.
Chang.

Menstrual induction injections, often used to stimulate menstruation in cases of delayed periods, can indeed have an impact on your menstrual cycle and flow. These injections typically contain hormones that help to regulate the menstrual cycle by promoting the shedding of the uterine lining. However, the effects can vary significantly from person to person, and several factors can influence how your body responds.

In your case, you received a menstrual induction injection on June 2nd due to a delayed period, and shortly thereafter, you experienced a significant illness with fever and required intravenous fluids and medication. This illness could have contributed to the changes in your menstrual flow. Stress, whether physical (like an illness) or emotional, can affect hormone levels and disrupt the menstrual cycle.
After receiving the injection, you reported light bleeding starting on June 5th, which is consistent with the expected response to the injection. The presence of blood clots on June 8th suggests that your body was shedding the uterine lining, which can happen after such treatments. However, the subsequent light spotting you experienced could be attributed to several factors:
1. Hormonal Fluctuations: The injection alters hormone levels, which can lead to irregular bleeding patterns. After the initial response to the injection, your body may still be adjusting to the hormonal changes, resulting in lighter than usual periods or spotting.

2. Illness Impact: The fever and illness you experienced could have further disrupted your hormonal balance, leading to changes in your menstrual flow. The body often prioritizes recovery from illness over reproductive functions, which can lead to lighter periods or spotting.

3. Uterine Lining Response: If the uterine lining was particularly thick prior to the injection, the body may have shed it in a way that doesn't follow the typical pattern of menstruation, leading to lighter bleeding or spotting.

4. Timing of the Cycle: If your cycle was already irregular prior to the injection, the hormonal changes might have exacerbated this irregularity, leading to unexpected bleeding patterns.

Regarding your question about whether the light spotting is due to the menstrual induction injection, it is quite possible. However, it is also essential to consider the impact of your recent illness. If the spotting continues or if you have concerns about your menstrual cycle, it would be wise to consult with your healthcare provider. They can assess your situation more thoroughly and determine if any further evaluation or treatment is necessary.

In summary, menstrual induction injections can affect your period and flow, and various factors, including recent illness and hormonal changes, can contribute to the irregularities you are experiencing. Monitoring your symptoms and maintaining open communication with your healthcare provider will help ensure that any underlying issues are addressed appropriately.
