Vaginal bleeding during sexual intercourse? Not related to menstruation?


During sexual intercourse with my boyfriend, there was a small amount of blood that came out, which I initially thought was my menstrual period.
However, afterward, there was no additional bleeding.
The date of our sexual activity was very close to my menstrual cycle, and there was significant friction during intercourse.
A day later, both my boyfriend and I experienced slight itching in our genital areas, and my boyfriend has a small area of broken skin on his genitalia.
Could this have a significant impact on our health? Is the blood that was expelled likely to be menstrual or could it be something else? Are there abortion pills that can be effective if taken half a month later?

Dr. Wang Jionglang reply Obstetrics and Gynecology


Hello Ms.
Lin: (1) A small amount of spot bleeding may be due to the shedding of the endometrium or superficial bleeding.
Clinically, it is not considered a serious condition and will not have a significant impact on health.
(2) The abortion pill currently approved for sale is RV-486, which is a controlled substance and should be taken under the guidance of a physician.

When it comes to bleeding during or after intercourse, it can be concerning and confusing, especially when the timing coincides with your menstrual cycle. Based on your description, there are several factors to consider regarding the potential causes of the bleeding and the associated symptoms.

Firstly, the bleeding you experienced could be due to a few different reasons. One possibility is that the bleeding is related to your menstrual cycle. If your intercourse occurred close to your expected period, it could be that the bleeding is an early sign of menstruation. However, since you mentioned that the bleeding was minimal and did not continue, it may not be typical menstrual bleeding.

Another potential cause of the bleeding could be trauma to the vaginal or cervical tissues. You noted that there was significant friction during intercourse, which could lead to micro-tears in the vaginal walls or even the cervix, especially if there was vigorous movement or insufficient lubrication. This type of injury can result in light bleeding and may also explain the itching and discomfort you and your boyfriend experienced afterward. The presence of a small cut or abrasion on your boyfriend's genital area could also contribute to irritation and discomfort.

In terms of health implications, while minor injuries to the vaginal area are generally not serious, they can lead to infections if not properly cared for. It’s essential to maintain good hygiene and avoid further irritation. If the bleeding persists, increases in volume, or if you experience significant pain, it would be wise to consult a healthcare professional for a thorough examination.

Regarding your question about the possibility of pregnancy, if you have not engaged in penetrative intercourse and there was no ejaculation, the likelihood of pregnancy is low. However, if there was any possibility of sperm coming into contact with the vaginal area, it is always prudent to take a pregnancy test if your period is late.

As for the use of abortion pills, it is crucial to understand that these medications should only be taken under the guidance of a healthcare provider. They are typically effective within a certain timeframe after conception, and taking them without medical supervision can lead to complications. If you suspect you might be pregnant and are considering this option, please consult a healthcare professional for appropriate advice and care.

In summary, the bleeding you experienced could be due to a variety of factors, including menstrual onset, trauma from intercourse, or other underlying conditions. If symptoms persist or worsen, seeking medical attention is advisable. Always prioritize your health and well-being by consulting with a healthcare provider for personalized advice and treatment.
