Could it be a pseudomenstruation?


Hello Dr.
Tsao: I apologize for bothering you again.
I am the one who asked about taking emergency contraception after intercourse on June 10th, and my expected period on the 30th did not arrive.
I took a pregnancy test on the night of June 6th, which showed one line.
However, last night around 11 PM, I suddenly felt like my period was starting.
This morning, when I checked the sanitary pad, there was only a little bit of flow, but I did feel something coming out when I used the restroom.
I have been feeling very fatigued lately, and there are some specific stress factors that I wonder might be affecting my menstrual cycle, as I usually have a heavier flow the next day.
Earlier this year in January, I also had a lighter period due to stress and saw a doctor who found a few fibroids and polyps.
I am concerned whether this situation means I should worry about the possibility of pregnancy.
I am a bit worried it might be a false period.
Thank you very much for your response, Dr.
Tsao.

When it comes to concerns about irregular periods and the possibility of pseudomenstruation, it’s important to understand the various factors that can influence menstrual cycles and the signs of early pregnancy. Based on your description, it seems you have experienced some irregularities and are understandably anxious about the implications for your health and potential pregnancy.

Firstly, pseudomenstruation, or what some might refer to as "false menstruation," can occur in early pregnancy. This is typically characterized by light spotting or bleeding that may resemble a menstrual period but is not a true menstrual cycle. It can happen due to implantation bleeding, which occurs when a fertilized egg attaches to the uterine lining. This type of bleeding is usually lighter and shorter in duration than a regular period. Given that you have taken emergency contraception, it’s crucial to note that these medications can also affect your menstrual cycle, potentially causing delays or changes in flow.

In your case, since you experienced a light flow after taking the emergency contraceptive pill, it is possible that this could be a result of hormonal changes induced by the medication. Stress and fatigue can also significantly impact your menstrual cycle. Stress can lead to hormonal imbalances that may cause irregularities in your cycle, including lighter periods or missed periods altogether.
Regarding your concerns about pregnancy, the negative pregnancy test you took on June 6 suggests that you were not pregnant at that time. However, if your period is irregular and you have had unprotected intercourse, it is always wise to take another pregnancy test if your period does not follow its expected pattern. If you experience any unusual symptoms, such as severe cramping or heavy bleeding, it is advisable to consult with a healthcare provider for further evaluation.

Additionally, you mentioned having fibroids and polyps. These conditions can also contribute to irregular bleeding and may affect your menstrual cycle. It is essential to have regular check-ups with your gynecologist to monitor these conditions, as they can sometimes lead to complications or influence your menstrual health.

In summary, while it is possible that what you are experiencing could be pseudomenstruation, it is also likely influenced by the emergency contraceptive you took, as well as stress and fatigue. If you continue to have irregular cycles or if you have concerns about potential pregnancy, I recommend consulting with your healthcare provider. They can perform a thorough evaluation, including a physical examination and possibly imaging studies, to determine the underlying causes of your symptoms and provide appropriate guidance.
Remember, maintaining open communication with your healthcare provider about your menstrual health and any changes you experience is key to managing your reproductive health effectively.
