If you have taken a medication to induce menstruation and your period has not started, can you switch to a medication to delay menstruation?
Hello doctor, my menstrual cycle usually starts around the 16th or 17th of each month.
The last time I had my period was on March 17, and I expect it to come around April 16.
However, I have an event on April 21, so I took over-the-counter menstrual induction medication (emergency contraceptive pill) on April 10.
It has been three days, and I still haven't gotten my period.
With the event approaching, I'm worried about a delay, so I would like to ask if I can switch to taking menstrual delay medication instead?

Hello, generally after taking menstrual induction medication, menstruation will occur in about 3-4 days.
If it still does not come, it is advisable to consult a gynecologist for further evaluation.
Wishing you good health.

More Info
Switching from induction medication to menstrual delay pills is a decision that should be made with caution and ideally under the guidance of a healthcare professional. Induction medications, such as emergency contraceptive pills (ECPs), are designed to prevent pregnancy after unprotected intercourse and can affect your menstrual cycle. On the other hand, menstrual delay pills, often containing hormones like norethisterone, are intended to postpone menstruation for a specific period.
First, it’s important to understand how these medications work. Induction medications can alter the timing of your menstrual cycle, potentially leading to a delay in your expected period. If you took an induction medication on April 10 and your expected period was around April 16, it’s not unusual for your cycle to be disrupted. The hormones in these medications can cause your body to react in unpredictable ways, including delaying your period.
If you are considering switching to menstrual delay pills, here are a few points to consider:
1. Timing and Hormonal Balance: Taking menstrual delay pills shortly after induction medication can further complicate your hormonal balance. It’s essential to allow your body some time to adjust after taking induction medication. Ideally, you should wait until your next cycle to start the delay pills, as this will help avoid potential side effects and ensure that your body is not overwhelmed by multiple hormonal changes at once.
2. Consultation with a Healthcare Provider: Before making any changes to your medication regimen, it’s crucial to consult with a healthcare provider. They can assess your specific situation, including your health history, the timing of your medications, and your upcoming schedule. They can provide personalized advice on whether it’s safe and appropriate for you to switch to menstrual delay pills.
3. Potential Side Effects: Both induction medications and menstrual delay pills can have side effects, including nausea, headaches, and changes in mood. Taking them in close succession may increase the likelihood of experiencing these side effects. A healthcare provider can help you weigh the risks and benefits based on your individual health profile.
4. Alternative Options: If your primary concern is the timing of your period due to an upcoming event, discuss alternative options with your healthcare provider. They may suggest other methods to manage your menstrual cycle that could be more suitable for your situation.
5. Monitoring Your Cycle: After taking induction medication, it’s essential to monitor your menstrual cycle closely. If your period does not arrive within a week of when it is expected, or if you experience unusual symptoms, you should seek medical advice.
In summary, while it may be tempting to switch to menstrual delay pills after taking induction medication, it’s essential to approach this decision with caution. Consulting with a healthcare provider will provide you with the best guidance tailored to your specific circumstances. They can help you navigate the complexities of hormonal medications and ensure that you make a safe and informed choice regarding your menstrual health.
