Bleeding after using tampons?


Hello, Doctor.
My period was almost over (on the 4th day), but I continued to bleed after using a tampon, and the flow was heavier than usual.
I noticed that when the tampon was not removed, there was a lot of bleeding, which made me feel like the bleeding was coming from outside the absorbent material, rather than being typical menstrual blood.
By the third day of use, I had stopped bleeding, but the amount of discharge increased significantly (yellowish-white) and the odor became stronger.
Recently, due to midterm exams, I have hardly drunk any water except for a cup of coffee in the morning.
I wonder if this is related to the stronger odor? Since we are in a girls' class, the teacher requires us to go swimming and insists that we use tampons or medication...
Thank you very much for your response, Doctor!

Hello: If there is a foreign object in the vagina, the bacteria residing in the vagina can easily proliferate, leading to an increase in yellow or white discharge, along with an unpleasant odor.
It is recommended to change tampons frequently and to minimize the number of days they are used.
Thank you for your message!

More Info


Understanding unusual bleeding after tampon use can be concerning, especially when it deviates from your normal menstrual pattern. Based on your description, it seems that you experienced increased bleeding after using a tampon, which is not typical, especially if your period was nearing its end. Here are some potential causes and considerations regarding your situation.

1. Tampon Use and Menstrual Flow: Tampons are designed to absorb menstrual flow, but if you were nearing the end of your period, the sudden increase in bleeding could be due to a few factors. Sometimes, the act of inserting or removing a tampon can irritate the vaginal walls, especially if they are sensitive or if the tampon is inserted incorrectly. This irritation can lead to spotting or increased bleeding.

2. Hormonal Fluctuations: Your menstrual cycle is regulated by hormones, and fluctuations can lead to changes in flow. If you were under stress, such as during midterms, this could potentially affect your hormonal balance, leading to unexpected changes in your menstrual flow.

3. Infection or Other Conditions: The change in the color and odor of your discharge could indicate an infection, such as bacterial vaginosis or a yeast infection. These conditions can cause changes in discharge and may also lead to irritation or inflammation, which could explain the unusual bleeding. It’s important to monitor for other symptoms, such as itching, burning, or unusual discomfort.

4. Dehydration: You mentioned that you had not been drinking much water. Dehydration can affect your body in various ways, including your menstrual cycle. While it may not directly cause unusual bleeding, it can lead to thicker cervical mucus, which might change the characteristics of your discharge.

5. Consulting a Healthcare Provider: Given the changes you’ve experienced, it would be wise to consult with a healthcare provider. They can perform a physical examination, possibly including a pelvic exam, to rule out infections or other underlying conditions. They may also recommend tests to check for any hormonal imbalances or other issues.

6. Tampon Use Guidelines: Ensure that you are using tampons correctly. Change them every 4 to 8 hours, and avoid using them overnight if possible. If you experience discomfort or unusual symptoms, consider switching to pads temporarily to see if your symptoms improve.

7. Monitoring Symptoms: Keep track of your symptoms, including the amount of bleeding, any pain or discomfort, and changes in discharge. This information will be helpful for your healthcare provider in diagnosing any potential issues.

In summary, while unusual bleeding after tampon use can be concerning, it can often be attributed to irritation, hormonal changes, or infections. It’s essential to stay hydrated and monitor your symptoms closely. If the unusual bleeding persists or if you develop additional symptoms, seeking medical advice is crucial to ensure your health and well-being.
