Postcoital bleeding?


After having intercourse for the first time with my girlfriend, she mentioned while showering that the amount of bleeding was similar to when she has her period.
She also said she felt a dull ache in her lower abdomen.
The activity we engaged in wasn't very intense.

Hello, the factors affecting intermenstrual bleeding are numerous, including age, environment, lifestyle, stress, emotional instability, weight changes, medications, postcoital contraceptives, diet, polycystic ovary syndrome, lesions of the uterus or cervix, infections, ovulation, pregnancy, and breastfeeding, among others.
It is recommended that if symptoms persist or worsen, you should consult a gynecologist to check for hormonal imbalances or other causes.
Thank you! Wishing you peace and health, Dr.

More Info


Post-intercourse bleeding can be a concerning experience for both partners, especially if it occurs unexpectedly. Understanding the potential causes and implications of this bleeding is essential for addressing any worries and ensuring both partners feel comfortable and informed.

Firstly, it's important to note that bleeding after intercourse can occur for several reasons. One of the most common causes is cervical irritation. During sexual activity, especially if it is the first time or if there is a lack of adequate lubrication, the cervix can be bumped or scraped, leading to minor bleeding. This is often accompanied by a sensation of discomfort or pressure in the lower abdomen, which your girlfriend described as feeling "dull."
Another potential cause of post-intercourse bleeding is hormonal fluctuations. If your girlfriend's menstrual cycle is irregular or if she is approaching her menstrual period, she may experience spotting or bleeding after intercourse. This can be due to changes in hormone levels that affect the uterine lining, making it more susceptible to bleeding.
Infections can also play a role in post-intercourse bleeding. Conditions such as cervicitis (inflammation of the cervix) or vaginitis (inflammation of the vagina) can cause bleeding during or after sexual activity. These infections can be due to sexually transmitted infections (STIs) or other non-STI-related infections. If your girlfriend has any unusual discharge, itching, or a strong odor, it would be wise for her to consult a healthcare provider for evaluation and treatment.

Additionally, if your girlfriend has a history of conditions such as endometriosis or fibroids, these can also lead to abnormal bleeding patterns, including post-intercourse bleeding. Endometriosis can cause the tissue that normally lines the uterus to grow outside of it, leading to pain and bleeding. Fibroids are non-cancerous growths in the uterus that can also cause heavy bleeding and discomfort.

While the bleeding may not be heavy and may resemble menstrual flow, it is crucial to monitor the situation. If the bleeding persists, increases in volume, or is accompanied by severe pain, it is advisable for your girlfriend to seek medical attention. A healthcare provider can perform a thorough examination, including a pelvic exam and possibly an ultrasound, to rule out any underlying issues.

In summary, post-intercourse bleeding can result from various factors, including cervical irritation, hormonal changes, infections, or underlying medical conditions. While it can be alarming, many cases are benign and resolve on their own. However, if the bleeding continues or is accompanied by concerning symptoms, it is essential to consult a healthcare professional for further evaluation and peace of mind. Communication with your partner about her symptoms and feelings is also vital to ensure both of you feel supported during this experience.
