When should I come?
Hello, doctor.
I have some questions to ask you: My last menstrual period started on November 24, and I took the emergency contraceptive pill for three consecutive days starting on December 11 (dispensed by a pharmacist).
On December 17, I experienced two days of bleeding that resembled a menstrual period (the bleeding was quite heavy).
1.
Is this bleeding normal, and can it be considered a menstrual period?
2.
If it is not a normal menstrual bleeding, when should I expect my menstrual period to arrive in December under normal circumstances?
3.
I have heard that menstrual cycles can become irregular after taking emergency contraceptive pills.
If my normal menstrual period in December is delayed by how many days should I seek medical attention for menstrual regulation?
Thank you, doctor, for taking the time to respond!

The emergency contraceptive pill contains hormones, and taking it may induce menstruation.
If you notice any abnormalities in the amount or duration of bleeding, it is best to consult a gynecologist for an examination.

More Info
When it comes to understanding the effects of emergency contraceptive pills (ECPs) on your menstrual cycle, it’s important to recognize that these medications can indeed cause changes in your menstrual pattern. Here’s a detailed breakdown of your questions regarding the timing and nature of your menstrual cycle after taking ECPs.
1. Is the bleeding after taking ECPs normal? Is it considered a period?
The bleeding you experienced on December 17, which occurred shortly after taking the emergency contraceptive pills, is likely a withdrawal bleed rather than a true menstrual period. ECPs, such as those containing levonorgestrel or ulipristal acetate, can cause hormonal changes that lead to this type of bleeding. It is not uncommon for this bleeding to resemble a menstrual period in terms of flow and duration. However, it is important to note that this withdrawal bleed does not count as a regular menstrual period.
2. If it’s not a normal menstrual period, when should I expect my next period?
After taking ECPs, your next menstrual period may be delayed or altered. Typically, if you have a regular menstrual cycle, you can expect your next period to arrive within a week or so of when it normally would. However, since ECPs can disrupt your cycle, it might come earlier or later than expected. If your cycle is usually regular, you might anticipate your next period around the time it typically occurs, but keep in mind that it could be affected by the ECPs.
3. How late should I wait to seek medical advice regarding my menstrual cycle?
If your period is more than a week late following the expected date, it would be advisable to take a pregnancy test to rule out pregnancy, especially if you had unprotected intercourse prior to taking the ECPs. If the test is negative and your period still does not arrive, or if you experience any unusual symptoms (such as severe pain or heavy bleeding), it would be wise to consult a healthcare provider. They can help assess your situation and determine if any further evaluation or treatment is necessary.
In summary, the bleeding you experienced after taking emergency contraception is likely a withdrawal bleed and not a regular menstrual period. Your next period may be delayed, and if it does not arrive within a week of when you expect it, consider taking a pregnancy test. If you have concerns about your menstrual cycle or experience any unusual symptoms, do not hesitate to reach out to your healthcare provider for guidance. It’s important to prioritize your health and well-being, especially after taking hormonal medications.
