Post-Intercourse Bleeding: Causes and Concerns for Fertility - Obstetrics and Gynecology

Postcoital bleeding


I had my ovulation period on July 6 and visited a gynecologist to check the size of my follicles.
The follicles were too large, so there was no chance of pregnancy this month.
On July 8, my husband and I decided to try for pregnancy, but after intercourse, I noticed some blood while wiping.
I'm unsure if the blood was caused by me or if it was from my husband's semen.
By the morning, the bleeding had stopped.
What could this issue be? If there were any other lesions, would they have been detected during the examination on July 6? Additionally, I had an ectopic pregnancy last year and lost one of my fallopian tubes.
Now, I want to see if there is a chance for pregnancy again.

On July 6, I was exactly at my ovulation period and went to the obstetrics and gynecology department to check the size of the follicle.
Due to the follicle being too large, there was no chance of pregnancy this month.
On July 8, my husband and I decided to try for pregnancy, but after intercourse, I noticed blood when wiping.
I'm not sure if it was caused by me or if it was from my husband's semen.
However, when I woke up in the morning, I found that there was no more bleeding.
What could be the issue?
Answer: The presence of blood after intercourse requires an internal examination and ultrasound to determine the cause.
Cervical erosion could certainly be one of the reasons.

Post-intercourse bleeding can be a concerning issue for many women, especially those who are trying to conceive. In your case, you experienced bleeding after intercourse on July 8, shortly after your ovulation period, which raises several questions regarding its cause and implications for fertility.

Firstly, it’s essential to understand that post-intercourse bleeding can arise from various sources. Common causes include:
1. Cervical or Vaginal Irritation: This is often the most benign explanation. The cervix and vaginal walls can be sensitive, especially around ovulation when hormonal changes can lead to increased blood flow and sensitivity. If there was vigorous intercourse, this could have caused minor trauma, leading to light bleeding.

2. Cervical Ectropion: This condition occurs when the cells from the inside of the cervical canal grow on the outside of the cervix. It can be more prone to bleeding, especially after intercourse. This condition is often benign but can cause discomfort and bleeding.

3. Hormonal Fluctuations: Given that you were in your ovulation phase, hormonal changes can lead to slight spotting. This is sometimes referred to as ovulation bleeding, which is typically light and short-lived.

4. Infections or Inflammation: Conditions such as cervicitis or vaginitis can cause bleeding after intercourse. If there were any signs of infection, such as unusual discharge or odor, it would be wise to consult a healthcare provider.

5. Polyps or Fibroids: These benign growths in the uterus or cervix can also lead to bleeding. While they may not have been detected during your recent ultrasound, they can sometimes be missed, especially if they are small.

6. Pregnancy-Related Issues: Although you mentioned that you were not able to conceive this cycle, it’s important to note that implantation bleeding can occur if conception happens shortly after ovulation. However, given your timeline, this seems less likely.

Regarding your concern about whether any underlying issues would have been detected during your ultrasound on July 6, it is possible that some conditions may not be visible or may develop after the examination. If there were no signs of significant abnormalities at that time, it is likely that the bleeding you experienced is not related to a serious underlying condition.

Given your history of an ectopic pregnancy and the loss of one fallopian tube, it is understandable that you are particularly concerned about your fertility. It is crucial to monitor your cycle and any unusual symptoms closely. If the bleeding recurs or if you experience any additional symptoms such as severe pain, unusual discharge, or prolonged bleeding, it would be advisable to seek medical attention promptly.

In terms of your fertility journey, it is essential to maintain open communication with your healthcare provider. They can offer guidance tailored to your specific situation, including potential fertility assessments or treatments if necessary. Additionally, tracking your ovulation and menstrual cycles can help you identify patterns and optimize your chances of conception.

In conclusion, while post-intercourse bleeding can be alarming, it is often due to benign causes. However, given your medical history and current concerns about fertility, it is always best to consult with your healthcare provider for personalized advice and reassurance. They can help you navigate your fertility journey and address any underlying issues that may arise.
