Pregnancy Risks After Taking Regulating Medication - Obstetrics and Gynecology

The sixth day of menstruation?


Hello Doctor: A few days ago, I went to the clinic to get a prescription for Progestin (for irregular menstruation).
I started taking it on the night of February 20 (this is my first time taking this medication).
On February 21, I had several sexual encounters with my boyfriend (on the sixth day of my period, with just a little left).
We used condoms throughout, and there were no tears, and although we used protection, I am still worried about the possibility of residual semen leaking.
What is the likelihood of pregnancy in this situation? Normally, I expect my period to come regularly next month after taking Progestin, right? I've heard that taking Progestin can make it easier to get pregnant; is that true? Thank you, Doctor :)

Hello, Miss: Thank you for your inquiry.
I would like to address your question and provide the following suggestions: In obstetrics and gynecology textbooks, the section on contraception does not include "condoms" for a specific reason.
Therefore, please consider using other effective contraceptive methods.
The correct use of "condoms" is to prevent sexually transmitted infections, rather than for contraception.
As for the other three questions, there are too many variables to provide definitive answers.
Lastly, I wish you peace and happiness~~

When considering the risks associated with taking regulating medication during pregnancy, it is essential to understand both the medication's effects and the timing of conception. In your case, you mentioned taking a medication called "普吉樂通" (likely a form of hormonal therapy for menstrual regulation) starting on February 20, and engaging in sexual activity shortly thereafter.
First, let's address the concern about the likelihood of pregnancy. If you used condoms consistently and they did not break, the chances of pregnancy are significantly reduced. However, no contraceptive method is 100% effective, and there is always a small risk of failure, especially if there is any concern about the condom's integrity or potential leakage.
Regarding the medication itself, "普吉樂通" is typically used to help regulate menstrual cycles, and it may contain hormones that can affect ovulation and the menstrual cycle. It is important to note that while some hormonal medications can influence fertility, they are not necessarily designed to increase the likelihood of conception. Instead, they aim to normalize hormonal levels and regulate menstrual cycles, which can, in some cases, help with fertility issues in the long term.
As for the timing of your menstrual cycle, if you are taking the medication as prescribed, it is expected that your next period should occur as anticipated. However, it is crucial to remember that hormonal medications can sometimes cause changes in the menstrual cycle, and it may take a few cycles for your body to adjust fully.
In terms of safety during pregnancy, if you were to become pregnant while taking this medication, it is essential to consult with your healthcare provider. Many medications have different classifications regarding their safety during pregnancy, and it is crucial to assess the specific risks associated with the medication you are taking.
For example, medications are often classified by the FDA into categories A, B, C, D, and X, based on their safety for use during pregnancy. Category A is the safest, while Category X indicates that the risks of using the medication in pregnancy outweigh any potential benefits. Without knowing the specific ingredients in "普吉樂通," it is difficult to provide a precise classification, but it is advisable to discuss this with your prescribing physician.

If you are concerned about the possibility of pregnancy or the effects of the medication, it is best to take a pregnancy test if your period is late or if you experience any unusual symptoms. Additionally, if you have any concerns about the medication's effects on a potential pregnancy, you should reach out to your healthcare provider for personalized advice.

In summary, while the use of "普吉樂通" may help regulate your menstrual cycle, the likelihood of pregnancy is low if you used condoms correctly. However, if you have any concerns about the medication or potential pregnancy, consulting with your healthcare provider is the best course of action. They can provide you with the most accurate information and guidance tailored to your specific situation.
