Is this menstruation?


Hello, doctor: I would like to ask, if after my period has ended I engage in sexual intercourse and then experience some bleeding, is that considered a period? It was only a small amount, about the size of a coin.
I'm a bit worried, thank you.

Yazhi, 40~49 year old female. Ask Date: 2013/11/08

Dr. Lin Wenbin reply Obstetrics and Gynecology


It is important to have regular examinations of the cervix, including Pap smears.
If there is any bleeding, it is also advisable to have a pelvic examination by a physician to check for any lesions such as cervical polyps.

More Info


Post-intercourse bleeding can be concerning, especially if it occurs after a period of menstruation. It is important to differentiate between normal menstrual bleeding and other potential causes of bleeding that may occur after sexual intercourse.
Firstly, if you have recently finished your menstrual cycle and then experienced bleeding after intercourse, it is unlikely to be a continuation of your menstrual period, especially if the bleeding is light and resembles spotting. Menstrual bleeding typically lasts several days and is usually more substantial than what you described.
There are several potential reasons for post-intercourse bleeding, including:
1. Cervical Irritation: The cervix can be sensitive, and during intercourse, it may become irritated, leading to light bleeding. This is particularly common if there is a lack of lubrication or if the intercourse was vigorous.

2. Hormonal Changes: Fluctuations in hormone levels can lead to changes in the menstrual cycle and may cause spotting or bleeding after intercourse.

3. Infections: Sexually transmitted infections (STIs) or other infections of the reproductive tract can cause inflammation and bleeding. If you have any other symptoms, such as unusual discharge, pain, or discomfort, it is important to consult a healthcare provider.

4. Polyps or Fibroids: These are benign growths in the uterus or cervix that can cause bleeding. They may not always present with symptoms, but they can lead to spotting after intercourse.

5. Pregnancy: If there is a possibility of pregnancy, any bleeding could be related to implantation bleeding, which can occur when a fertilized egg attaches to the uterine lining. However, this typically occurs around the time of your expected period.

6. Other Medical Conditions: Conditions such as endometriosis or pelvic inflammatory disease (PID) can also lead to bleeding after intercourse.

Given your concern, it is advisable to monitor the situation. If the bleeding persists, increases in volume, or is accompanied by other symptoms such as pain, fever, or unusual discharge, you should seek medical attention promptly. A healthcare provider can perform a thorough evaluation, which may include a pelvic exam, ultrasound, or other diagnostic tests to determine the cause of the bleeding.

In summary, while light bleeding after intercourse may not always indicate a serious issue, it is essential to pay attention to your body and seek medical advice if you have any concerns. Regular gynecological check-ups are also important for maintaining reproductive health and addressing any potential issues early on.
