The relationship between taking cold medicine and menstrual irregularities?


I have had two severe colds in the past month, during which I first took Western medicine for two weeks and then switched to traditional Chinese medicine for over two weeks.
This is the first time in my life I have taken Chinese medicine, and last week I also consumed ginseng.
Now, my menstrual period is delayed; I only have some sporadic brown discharge that resembles menstrual blood, and it is already eight days late.
I have been tracking my basal body temperature, and my estimated ovulation day was around the 13th.
Could this be related to my continuous use of cold medication or traditional Chinese medicine?

Pregnancy should be ruled out first, as it is possible to experience light bleeding during pregnancy.
If pregnancy is not the case, then certain medications can indeed affect menstrual flow.

The relationship between cold medications and menstrual irregularities is a topic of interest for many individuals experiencing changes in their menstrual cycles. In your case, it appears that you have been dealing with a significant cold for an extended period, which has led you to take both Western and traditional Chinese medicines. It is understandable to be concerned about how these medications may affect your menstrual cycle, especially since you are experiencing a delay in your period and unusual discharge.

Firstly, it is important to recognize that various factors can influence menstrual cycles, including stress, illness, changes in routine, and medications. When the body is under stress from an illness, such as a cold, it can lead to hormonal fluctuations that may disrupt the regularity of your menstrual cycle. The body prioritizes recovery from illness, which can sometimes result in delayed ovulation or changes in the menstrual cycle.

Regarding the medications you have taken, both Western cold medications and traditional Chinese medicines can have side effects that may impact your menstrual cycle. Common over-the-counter cold medications often contain antihistamines, decongestants, and pain relievers. Antihistamines, for example, can cause drowsiness and may have an impact on hormonal balance in some individuals. Additionally, certain decongestants can affect blood flow and circulation, which might indirectly influence menstrual regularity.

On the other hand, traditional Chinese medicine (TCM) approaches often involve herbal remedies that can have varying effects on the body. Some herbs may help to regulate menstrual cycles, while others could potentially lead to changes in hormonal levels. For instance, ginseng, which you mentioned consuming, is known for its stimulating properties and may affect hormonal balance, particularly if taken in large quantities or over an extended period.

It is also worth noting that lifestyle factors, such as stress, diet, and sleep patterns, can significantly impact menstrual cycles. If you have been feeling unwell, your body may be under additional stress, which can further contribute to irregularities.

In your specific case, the absence of your period for eight days, along with the presence of brown discharge, could be attributed to several factors, including the medications you have taken, the stress of being ill, and potential hormonal changes. It is essential to monitor your symptoms closely. If your period does not resume soon or if you experience any additional concerning symptoms, such as severe pain or heavy bleeding, it would be advisable to consult with a healthcare professional. They can provide a more thorough evaluation, including potential hormonal assessments, to determine the underlying cause of your menstrual irregularities.

In summary, while cold medications and herbal remedies can potentially influence menstrual cycles, it is crucial to consider the broader context of your health, stress levels, and lifestyle. If you have ongoing concerns, seeking medical advice will help ensure that any underlying issues are addressed appropriately.

The cold medication has little effect; it could possibly be due to pregnancy or other reasons (such as poor ovarian function, elevated prolactin levels, or even an ectopic pregnancy). It is essential to visit a gynecology clinic for examination.
