Unusual Bleeding After Emergency Contraceptive: Side Effects or Not? - Obstetrics and Gynecology

Abnormal bleeding five days after taking the medication Anjing (安錠) – could this be a side effect of the drug?


Last Saturday, I had unprotected intercourse (my menstrual cycle just ended on Friday).
However, I was worried, so I bought emergency contraception and took it at midnight on Saturday and again at noon on Sunday.
This morning, five days later, I experienced bleeding that resembles my menstrual cycle, and the blood is bright red.
Is this a side effect of the medication? Also, my menstrual cycles have been regular, around 29 days.
Will my next period come earlier? Additionally, I often experience vaginal inflammation; it flares up whenever I stay up late.
Is there a way to completely cure this? I don't have itching, but I do have discharge, and if my schedule is slightly irregular, there is an unusual odor.

Hello: 1.
Taking emergency contraceptive pills may result in withdrawal bleeding within a week, but this bleeding does not necessarily indicate successful contraception.
If your next period is delayed, you should take a pregnancy test.
2.
If you notice an unusual odor in your vaginal discharge, it may be a sign of bacterial vaginosis.
Please visit the Department of Obstetrics and Gynecology at Hsinchu Hospital as soon as possible.

More Info


When it comes to unusual bleeding after taking emergency contraceptive pills (ECPs), it is important to understand that this can be a common side effect of the medication. ECPs, such as Plan B or Ella, contain hormones that can disrupt your normal menstrual cycle. After taking ECPs, it is not unusual to experience bleeding that resembles a menstrual period, which can occur within a few days to a week after taking the medication. This bleeding is often referred to as "withdrawal bleeding" and is a result of the hormonal changes induced by the pill.

In your case, since you took the emergency contraceptive pill on Saturday night and experienced bleeding five days later, this could very well be a side effect of the medication. The blood being bright red is also typical, as it often indicates fresh blood. However, it is important to monitor the bleeding. If it becomes excessively heavy or is accompanied by severe pain, it would be advisable to seek medical attention.

Regarding your menstrual cycle, taking emergency contraception can sometimes lead to changes in your cycle. It is possible that your next period may come earlier or later than expected. The hormonal fluctuations caused by the ECP can affect the timing of ovulation and menstruation. If your cycle has been consistently around 29 days, it may still return to that pattern after the effects of the ECP wear off, but it is not guaranteed.

As for your recurrent vaginal inflammation, it is essential to address this with your healthcare provider. Chronic vaginal inflammation can be caused by various factors, including infections, allergies, or irritants. Since you mentioned that you experience this condition when your routine is disrupted, it could be related to changes in your immune response or exposure to irritants. While you do not experience itching, the presence of unusual discharge and odor suggests that there may be an underlying issue that needs to be evaluated.

To manage and potentially resolve recurrent vaginal inflammation, consider the following steps:
1. Consult a Healthcare Provider: A thorough examination and possibly some tests (like a swab or culture) can help identify the cause of your symptoms. This is crucial for determining the appropriate treatment.

2. Maintain Good Hygiene: Ensure that you are practicing good vaginal hygiene. This includes wearing breathable cotton underwear, avoiding douching, and using mild, unscented soaps.

3. Diet and Lifestyle: A balanced diet and a healthy lifestyle can support your immune system. Staying hydrated and managing stress can also play a role in reducing inflammation.

4. Probiotics: Some studies suggest that probiotics may help maintain a healthy vaginal flora, which can prevent infections and inflammation.

5. Avoid Irritants: Identify and avoid any potential irritants, such as scented products, harsh soaps, or certain fabrics that may exacerbate your symptoms.

6. Follow-Up: Regular follow-ups with your healthcare provider can help monitor your condition and adjust treatment as necessary.

In conclusion, while unusual bleeding after taking emergency contraception can be a side effect, it is essential to monitor your symptoms and consult with a healthcare provider if you have concerns. Additionally, addressing recurrent vaginal inflammation with a healthcare professional will help you find a long-term solution.
