Post-Pill Bleeding: Is It Your Period? - Obstetrics and Gynecology

Bleeding occurs 7 days after taking the emergency contraceptive pill?


Hello, doctor! My last menstrual period was from April 22 to 28, with a cycle length of about 32-34 days.
On May 2, I had intercourse, and the condom accidentally broke.
I took the emergency contraceptive pill, Ella (ulipristal acetate), within an hour after the incident.
On May 8, I experienced some bleeding, which was about the same amount as on the third day of my period.
As of May 9, I am still experiencing bleeding (without the breast tenderness I usually have).
Could you please advise if this is my menstrual period or a normal side effect? Will my next period arrive on schedule? (My next expected period is around May 22).
Thank you, doctor!

1.
After taking emergency contraception, menstruation may be disrupted, resulting in abnormal uterine bleeding, which should not be considered as "menstruation." 2.
Normal.
3.
It may be delayed.

More Info


When it comes to understanding post-pill bleeding, especially after taking emergency contraception like Ella (also known as ulipristal acetate), it's essential to recognize how hormonal fluctuations can affect your menstrual cycle. Based on your description, you experienced a menstrual period from April 22 to April 28, with a cycle length of approximately 32 to 34 days. After having unprotected intercourse on May 2 and taking the emergency contraceptive pill within an hour, you noticed bleeding starting on May 8.

1. Is the bleeding you experienced on May 8 your period?
The bleeding you are experiencing could be a side effect of the emergency contraceptive pill rather than your regular menstrual period. Emergency contraceptive pills can cause changes in your menstrual cycle, including spotting or bleeding that may occur earlier than expected. This bleeding is often lighter than a typical period and may not follow the usual pattern of your menstrual cycle. Since you mentioned that the bleeding is similar to what you experience on the third day of your period, it is possible that it is a withdrawal bleed caused by the hormonal changes induced by the pill.

2. Will your next period arrive on time?
After taking emergency contraception, your next period may be delayed or arrive earlier than expected. In your case, since your next expected period is around May 22, it could still arrive on time, but it may also be affected by the hormonal changes from the emergency contraceptive. It's not uncommon for women to experience irregularities in their cycle after taking such medication. If your period does not arrive by the expected date, you may want to take a pregnancy test to rule out pregnancy, especially if you have any concerns.

3. What should you expect moving forward?
It’s essential to monitor your bleeding patterns over the next few days. If the bleeding continues and resembles your typical menstrual flow, it could indicate that your body is responding to the hormonal changes. However, if you experience heavy bleeding, severe pain, or any other concerning symptoms, it would be wise to consult a healthcare provider.

4. Understanding hormonal impacts:
Emergency contraceptive pills work primarily by delaying ovulation, preventing fertilization, or preventing implantation of a fertilized egg. These hormonal changes can lead to various side effects, including nausea, breast tenderness, and changes in bleeding patterns. It’s crucial to remember that while these pills are effective, they are not intended for regular use and should not replace regular contraceptive methods.

5. When to seek medical advice:
If your bleeding does not resolve, becomes heavier, or if you have any other symptoms that concern you, such as severe abdominal pain or unusual discharge, it is advisable to seek medical attention. Additionally, if you have not had your period by the time it is due, taking a pregnancy test can provide clarity.

In conclusion, the bleeding you are experiencing is likely a response to the emergency contraceptive pill rather than your regular menstrual period. Keep track of your symptoms, and if you have any concerns, don’t hesitate to reach out to a healthcare professional for personalized advice.
