Abnormal bleeding


On Sunday, the day after my period ended, my boyfriend and I had intercourse with a condom, and since Tuesday, I've been experiencing abnormal bleeding (mostly a reddish watery discharge).
It is now Thursday, and it is still occurring.
What could be the cause of this? I would appreciate your guidance, doctor.

Hello: The sites of post-coital bleeding are primarily the hymen, vagina, cervix, and endometrium.
(1) Hymen: A hymenal opening that is too small or vigorous sexual activity can cause laceration and bleeding even in non-virgins.
(2) Vagina: Similar to the hymen, vigorous sexual activity, the presence of foreign objects, or the use of sex toys can lead to vaginal lacerations and bleeding.
(3) Cervix: This area is the most common cause of post-coital bleeding.
Cervical erosion can lead to the rupture of microvessels, resulting in bleeding.
Causes include cervical ectropion, cervicitis, and notably, precancerous lesions and cervical cancer.
Additionally, cervical polyps are also common causes of post-coital bleeding.
(4) Endometrium: Generally, stress, ovulation, the use of an intrauterine device, or poor follicular development during the cycle can lead to insufficient secretion of female hormones, causing endometrial instability and subsequent bleeding after trauma.
Furthermore, endometrial polyps can also cause post-coital bleeding.
If post-coital bleeding occurs, it is advisable to consult a gynecologist for a pelvic examination and ultrasound to determine the cause.
A Pap smear may also be necessary to rule out precancerous changes and malignancies.
Thank you for your inquiry!

More Info


Abnormal bleeding after menstruation, often referred to as intermenstrual bleeding, can be concerning and may arise from various causes. In your case, experiencing abnormal bleeding shortly after your menstrual period, especially if it is bright red and watery, warrants attention. Here are some potential causes and guidance on what you should consider:

Potential Causes of Abnormal Bleeding
1. Hormonal Imbalances: Fluctuations in hormone levels can lead to irregular bleeding. This can occur due to stress, changes in weight, or hormonal contraceptives. If you have recently started or changed any birth control methods, this could be a contributing factor.

2. Ovulation: Some women experience light spotting during ovulation, which occurs about midway through the menstrual cycle. This is typically light and may be accompanied by mild cramping.

3. Infections: Sexually transmitted infections (STIs) or pelvic inflammatory disease (PID) can cause abnormal bleeding. If you have any other symptoms such as unusual discharge, pain during intercourse, or fever, it is essential to seek medical attention.

4. Polyps or Fibroids: These benign growths in the uterus can lead to irregular bleeding. They are often non-cancerous but can cause discomfort and heavy bleeding.

5. Endometriosis: This condition occurs when tissue similar to the lining of the uterus grows outside of it, leading to pain and abnormal bleeding.

6. Pregnancy-related Issues: If there is a possibility of pregnancy, any bleeding could be a sign of a miscarriage or an ectopic pregnancy. It is crucial to take a pregnancy test if you suspect you might be pregnant.

7. Other Medical Conditions: Conditions such as thyroid disorders, clotting disorders, or certain cancers can also lead to abnormal bleeding.


Guidance and Recommendations
1. Monitor Symptoms: Keep track of your bleeding pattern, including the amount, color, and any accompanying symptoms such as pain or unusual discharge. This information will be helpful for your healthcare provider.

2. Consult a Healthcare Provider: Given that your bleeding has persisted for several days, it is advisable to consult a healthcare provider. They may perform a physical examination, pelvic exam, or ultrasound to determine the cause of the bleeding.

3. Consider a Pregnancy Test: If there is any chance you could be pregnant, take a home pregnancy test. If positive, contact your healthcare provider for further evaluation.

4. Avoid Self-Diagnosis: While it is helpful to research and understand potential causes, self-diagnosing can lead to unnecessary anxiety. A healthcare professional can provide a proper diagnosis and treatment plan.

5. Stay Informed: Educate yourself about your menstrual cycle and what constitutes normal versus abnormal bleeding. This knowledge can empower you to seek help when necessary.


Conclusion
Abnormal bleeding after menstruation can have various causes, and while some may be benign, others may require medical intervention. It is essential to pay attention to your body and seek medical advice if you experience prolonged or concerning symptoms. Early diagnosis and treatment can help manage any underlying conditions effectively and ensure your reproductive health is maintained.
