Postcoital bleeding


Hello doctor, my last menstrual period started on August 31.
I had sexual intercourse on August 24, and afterward, I noticed dark-colored discharge.
For the next three to four days, I had some brown discharge that gradually became lighter until my period officially started on the 31st.
This month, during sexual intercourse on September 21, I noticed pink discharge on the condom, which also dripped onto the floor.
In the following one or two days, I had a little bit of light brown discharge that became lighter.
Additionally, I've been experiencing dull menstrual cramps in my lower abdomen.
Could you please explain what might be the cause of my bleeding? Could it be ovulation bleeding or hormonal imbalance? However, there was no bleeding after sexual intercourse following my period.
Under what circumstances could bleeding occur after intercourse before menstruation? (My period has not started yet.)

Fang, 20~29 year old female. Ask Date: 2019/09/25

Dr. Huang Yiwen reply Obstetrics and Gynecology


Hello Ms.
Fang: The causes of bleeding during sexual intercourse in young women are often related to cervical inflammation, cervical erosion, or may occur around ovulation or just before menstruation.
Of course, some cases could be due to menstrual irregularities or early pregnancy.
To determine the exact cause, a medical examination by a doctor is necessary.
If you are concerned, it would be advisable to visit a gynecologist.

Post-sexual bleeding can be a concerning symptom for many women, and understanding its potential causes is crucial for addressing any underlying health issues. Based on your description, there are several factors to consider regarding the bleeding you experienced after sexual intercourse.

Firstly, it is important to differentiate between various types of bleeding. The dark brown discharge you observed after sexual activity could be old blood, which is often a result of the shedding of the uterine lining. This can occur for several reasons, including hormonal fluctuations, which can lead to irregular bleeding patterns. If you experienced this type of discharge leading up to your menstrual period, it may simply be a sign that your body is preparing for menstruation.

In your case, the pink discharge observed during sexual activity could indicate several possibilities. One common cause is cervical irritation, which can occur during intercourse, especially if there is vigorous movement or if the cervix is sensitive. This irritation can lead to minor bleeding, which may appear as pink or light red discharge. Additionally, if there are any underlying conditions such as cervical polyps or infections, these could also contribute to post-coital bleeding.

Another possibility is that the bleeding could be related to hormonal changes. If you have a history of irregular menstrual cycles, it is possible that your body is experiencing fluctuations in hormone levels, which can lead to unexpected bleeding. This is particularly relevant if you have not had a consistent menstrual cycle, as hormonal imbalances can cause the endometrium (the lining of the uterus) to shed at irregular intervals.

Regarding your question about whether this could be ovulation bleeding, it is indeed possible. Some women experience light spotting during ovulation, which typically occurs about 14 days before the start of their next period. However, this is usually a very light discharge and not typically associated with significant bleeding during or after intercourse.

As for your concern about bleeding before menstruation, it is not uncommon for some women to experience spotting or light bleeding in the days leading up to their period. This can be due to hormonal changes as the body prepares for menstruation. If you have had sexual intercourse close to your expected menstrual period, the hormonal shifts could potentially trigger this type of bleeding.

In summary, the causes of post-sexual bleeding can range from benign cervical irritation to hormonal imbalances or even underlying medical conditions. It is essential to monitor your symptoms closely. If the bleeding persists, becomes heavier, or is accompanied by other symptoms such as severe pain, fever, or unusual discharge, it is advisable to seek medical attention. A healthcare provider can perform a thorough evaluation, including a pelvic exam and possibly imaging studies, to determine the exact cause of your symptoms and recommend appropriate treatment.

In conclusion, while occasional post-sexual bleeding can be normal, especially in the context of hormonal fluctuations or minor cervical irritation, persistent or concerning symptoms warrant further investigation. Keeping track of your menstrual cycle and any associated symptoms can provide valuable information for your healthcare provider in diagnosing and managing your condition effectively.
