Menstrual Irregularities and Medication Risks During Pregnancy

Menstrual irregularities, issues with menstrual regulation medications?

1.
The menstrual cycle has been stable for the past six months, but the amount of menstrual flow varies.
I had my menstrual cycle from March 30 to April 5, but the flow was light for the first three days.
On April 12, I noticed a small amount of bleeding when wiping after using the restroom, but it was minimal and did not soak the sanitary pad.

2.
I visited the doctor on April 14.
After a pelvic examination, no obvious abnormalities were found.
The doctor indicated that there was no ovulation and diagnosed me with irregular menstruation, recommending menstrual regulation.
After confirming that I was not pregnant, the doctor prescribed Estromon F.C.
Tablets and SHiton S.C.
Tablets, one tablet each in the morning and evening, to be taken for seven days starting the evening of April 14.
3.
On April 17, I had unprotected sexual intercourse.
I researched and found that Estromon is classified as category 'X' for pregnancy risk.
I would like to ask the doctor if there is a possibility of pregnancy.
Should I use contraception during the medication period? I currently have a desire to conceive.
Thank you!

When it comes to understanding menstrual irregularities and the risks associated with medication during pregnancy, it is essential to consider both the physiological aspects of menstruation and the pharmacological implications of the medications involved.

Firstly, menstrual irregularities can manifest in various forms, including changes in cycle length, flow volume, and the presence of spotting or bleeding outside of the expected menstrual period. In your case, you mentioned a stable cycle over the past six months, followed by a period with varying blood flow and a subsequent light spotting episode. These symptoms can be indicative of hormonal fluctuations, which may be influenced by various factors such as stress, diet, or underlying medical conditions.

Regarding the medications you were prescribed, Estromon F.C. Tablet and SHiton S.C. Tablet, it is crucial to understand their classifications and potential effects. Estromon, which contains estrogen, is classified as Category X by the FDA. This classification indicates that studies in animals or humans have demonstrated fetal abnormalities, and the risks involved in using the drug in pregnant women clearly outweigh any potential benefits. Therefore, if there is a possibility of pregnancy, it is highly advised to avoid using this medication.

On the other hand, SHiton S.C. Tablet, which typically contains a combination of hormones or other active ingredients, may have different implications. However, without specific information on its components, it is challenging to provide a definitive classification. It is essential to consult with your healthcare provider about the safety of this medication during potential pregnancy.

Given that you had unprotected sexual intercourse on April 17, after starting the medications, there is a possibility of pregnancy. If you are actively trying to conceive, it is crucial to communicate this with your healthcare provider. They can guide you on the appropriate steps to take, including whether to continue or discontinue the medications based on your current situation.

In general, when considering medication during the preconception period or early pregnancy, it is vital to consult with a healthcare professional. They can provide personalized advice based on your medical history, current medications, and any potential risks to both you and a developing fetus. If you suspect you might be pregnant, it is advisable to take a pregnancy test and discuss your findings with your doctor as soon as possible.

In summary, while menstrual irregularities can be concerning, understanding the implications of any medications you are taking is equally important. Always prioritize open communication with your healthcare provider, especially when planning for pregnancy or if you suspect you may be pregnant. They can help you navigate the complexities of medication use and reproductive health, ensuring the best possible outcomes for you and your future family.
