Fertility Issues and the Use of Menstrual Regulation Medications


Hello, Doctor.
I would like to ask about the use of menstrual delay medication and pregnancy issues.
I had a miscarriage surgery on February 17, and my period returned on March 23.
Since I will be traveling abroad at the end of April, there is a high possibility that my menstrual cycle, which is usually around 30 days, will coincide with my trip.
However, I also want to take advantage of every opportunity for conception.
The obstetrician I consulted mentioned that menstrual delay medication could affect the embryo, so I should avoid pregnancy this cycle and start trying again next time.
However, after researching online, I found that taking progesterone would not have an impact even if pregnancy occurs.
The prescribed medications are as follows: ESTROMON 0.625 mg and Norina.

1.
Will these medications affect pregnancy?
2.
If so, could you suggest alternative medications?
3.
I am currently tracking my basal body temperature and using ovulation test strips.
If I identify ovulation and count 14 days, I can estimate my next period.
Can I also assess whether I need to take menstrual delay medication on my own?
Thank you for taking the time to respond.

AK, 30~39 year old female. Ask Date: 2019/04/01

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, if you are concerned, you may consider taking natural progesterone instead of using ESTROMON to address the issue.
If you still have doubts, you can consult your regular obstetrician-gynecologist.
Wishing you good health.

More Info


When considering the impact of medications on pregnancy, particularly in the context of menstrual delay medications, it is crucial to understand the potential risks and benefits involved. In your case, you mentioned having undergone a miscarriage on February 17 and subsequently having your menstrual cycle return on March 23. You are now contemplating the use of medications to delay your menstrual cycle in order to optimize your chances for conception during your next cycle.

1. Impact of Delay Medications on Pregnancy: Medications such as progestins (like Estromon) are often prescribed to manage menstrual cycles. While these medications can help regulate or delay menstruation, their effects on early pregnancy can vary. Generally, if a woman becomes pregnant while taking progestins, these medications are not typically associated with significant risks to the developing embryo. In fact, progestins are sometimes used to support early pregnancy in women who have a history of miscarriage or hormonal imbalances. However, it is essential to consult with your healthcare provider regarding the specific medications you are taking, as individual responses can differ.

2. Alternative Medications: If your healthcare provider has advised against using menstrual delay medications while trying to conceive, it is essential to discuss alternative options. For instance, if the goal is to manage your menstrual cycle without negatively impacting your chances of conception, your doctor may suggest lifestyle modifications, natural remedies, or other medications that are deemed safer during the conception phase. Always ensure that any medication you consider is discussed with your healthcare provider, who can provide personalized advice based on your medical history and current health status.

3. Monitoring Ovulation and Menstrual Cycles: You mentioned that you are tracking your basal body temperature and using ovulation test strips. This is an excellent approach to understanding your cycle and identifying your fertile window. If you can accurately predict ovulation, you may not need to take menstrual delay medications at all. If you are able to conceive naturally, it is generally advisable to avoid unnecessary medications during this time. If you find that your cycle is irregular or if you have concerns about timing, it may be beneficial to have a follow-up consultation with your healthcare provider to discuss your findings and any necessary adjustments to your approach.

In summary, while medications to delay menstruation can be effective, their use during the conception phase should be approached with caution. It is essential to have open communication with your healthcare provider about the medications you are considering, their potential impacts on pregnancy, and any alternative options that may be available. Your proactive approach to tracking your cycle and understanding your body is commendable, and it will serve you well as you navigate this journey toward conception. Remember, the goal is to create the healthiest environment for a potential pregnancy, and your healthcare provider is your best resource for achieving that.

Hello, Miss :) In theory, if a doctor prescribes medication for you that lasts three days, the likelihood of it affecting your menstrual cycle should be minimal. Unless you are pregnant, your menstrual period should arrive next month.
