Bleeding during intercourse?


Hello, doctor: I have been worried about this issue.
My period was late this time.
Because of my concern, I took a urine test and a blood test, but everything came back normal.
A few days later, my period started (3 days late).
Then, 7 to 10 days after my period, I had intercourse with my boyfriend and suddenly experienced bleeding (quite a bit).
Could you please help me understand what this could be? Is there a possibility of pregnancy?

Dr. Li Guanghan reply Obstetrics and Gynecology


Hello: You should come for an examination immediately.
If the urine pregnancy test is negative, pregnancy can be ruled out.
The cause of the bleeding will need to be investigated further.

Post-intercourse bleeding can be a concerning issue for many women, and it is understandable that you are feeling anxious about it, especially after a late period. Let’s break down the possible causes of this bleeding and address your concerns regarding pregnancy.

Firstly, it is important to note that post-intercourse bleeding can occur for several reasons. One common cause is cervical irritation. During intercourse, the cervix can be bumped or irritated, especially if there is any dryness or lack of lubrication. This irritation can lead to minor bleeding, which may appear as bright red blood. If the bleeding is light and resolves quickly, it is often not a cause for concern.

Another potential cause of post-intercourse bleeding is hormonal fluctuations. Your menstrual cycle can be influenced by various factors, including stress, changes in weight, or hormonal imbalances. Since you mentioned that your period was late and you have experienced some irregularities in your cycle, it is possible that hormonal changes are contributing to the bleeding you are experiencing after intercourse.

In some cases, post-coital bleeding can be associated with infections, such as cervicitis or vaginitis. These conditions can cause inflammation of the cervix or vagina, leading to bleeding during or after intercourse. If you have any accompanying symptoms, such as unusual discharge, itching, or a foul odor, it would be wise to consult a healthcare provider for further evaluation.

Another consideration is the possibility of polyps or fibroids. These benign growths in the cervix or uterus can sometimes cause bleeding, particularly after intercourse. While they are generally not serious, they can lead to discomfort and should be evaluated by a healthcare professional if they are suspected.

Regarding your concern about pregnancy, since you have already taken urine and blood tests that returned normal results, it is less likely that you are pregnant. However, if you continue to experience unusual bleeding or if your symptoms change, it may be worth repeating a pregnancy test or consulting with a healthcare provider for further evaluation.

It is also essential to consider the timing of your bleeding. If it occurs consistently after intercourse, it may be worth keeping a record of when it happens, how much bleeding occurs, and any other symptoms you may experience. This information can be helpful for your healthcare provider in determining the underlying cause.

In summary, while post-intercourse bleeding can be alarming, it is often due to benign causes such as cervical irritation, hormonal fluctuations, or infections. If the bleeding persists, increases in volume, or is accompanied by other concerning symptoms, it is advisable to seek medical attention. Your health and peace of mind are important, and a healthcare provider can help you navigate these concerns effectively.
