Hello Doctor, I have a habit of masturbating.
A few weeks ago, I started a sexual relationship with my girlfriend.
We had intercourse a couple of times without a condom, but mostly we used one.
Last week, I noticed some unknown fluid on my underwear, and since it dried up, I can't tell what color it was.
It's definitely not urine.
This morning, I noticed a small amount of blood in my urine, but it's not very much.
Should I see a doctor about this? Also, I've been experiencing a cold lately; could it be related? Thank you, Doctor.

When it comes to the presence of blood in urine, also known as hematuria, it is essential to understand that this symptom can arise from a variety of causes, ranging from benign to serious medical conditions. Given your situation, where you have experienced blood in your urine after engaging in sexual activity and have also been feeling unwell, it is advisable to seek medical attention promptly.


Potential Causes of Hematuria
1. Infections: Urinary tract infections (UTIs) are a common cause of hematuria, especially in sexually active individuals. Symptoms may include a burning sensation during urination, frequent urination, and abdominal pain. If you have been experiencing cold-like symptoms, it is possible that your immune system is compromised, making you more susceptible to infections.

2. Trauma: Engaging in sexual activity can sometimes lead to minor trauma to the urinary tract, which may result in bleeding. This is particularly true if there was any vigorous activity or if there are underlying conditions that make the tissues more susceptible to injury.

3. Kidney Stones: These can cause bleeding as they move through the urinary tract. Symptoms may include severe pain in the back or side, nausea, and changes in urination.

4. Sexually Transmitted Infections (STIs): Certain STIs can lead to inflammation and bleeding in the urinary tract. If you have had unprotected sex, it is crucial to consider this possibility.

5. Other Medical Conditions: Conditions such as glomerulonephritis, tumors, or other kidney issues can also lead to hematuria. While these are less common, they are serious and require medical evaluation.


When to Seek Medical Attention
Given the presence of blood in your urine, it is important to consult a healthcare provider, especially if you experience any of the following:
- Persistent blood in urine
- Pain during urination
- Abdominal or flank pain
- Fever or chills
- Any other unusual symptoms

What to Expect During a Medical Evaluation
When you visit a healthcare provider, they will likely perform a thorough evaluation, which may include:
- Medical History: Discussing your symptoms, sexual history, and any recent illnesses or medications.

- Physical Examination: A physical exam to check for any signs of infection or other issues.

- Urinalysis: A urine test to check for signs of infection, blood, or other abnormalities.

- Imaging Studies: If necessary, imaging studies such as an ultrasound or CT scan may be ordered to visualize the urinary tract and identify any underlying issues.


Conclusion
In summary, while occasional blood in urine can sometimes be benign, given your recent sexual activity and current symptoms, it is prudent to seek medical attention. Early diagnosis and treatment are crucial to address any potential underlying conditions effectively. Do not hesitate to reach out to a healthcare provider for a thorough evaluation and appropriate care. Your health and well-being are of utmost importance, and addressing these symptoms early can lead to better outcomes.
