Clear sticky substance blocked my urine?

[KKdark]

I was recently diagnosed with urinary tract infection after i noticed blood came out of my penis after urinating. The urine test indicated that white blood cells was high in my urine so the doctor prescribed antibiotics for me to treat the uti. I took antibiotics for 1 week and had another urine test after and it came back indicating that the level of white blood cells has normalized. A week and a half later (today) I noticed a clear sticky substance was at the tip of my penis making my pee stream like a sprinkler instead of a steady stream. I touched the substance and it was sticky.

Could it be sperm or was it a discharge? Is there still a possibility that i can have an std after taking two urine test that came back negative?

Additional details:
my last sexual encounter was probably a day and a half before my first urine test which said that i had uti and 11 days before the second one which said that the white blood cell level normalized.

I masturbated the night before but didn't get in to it and didn't finish. So I didn't ejaculate.

Doubt a STD then

Well it just had happened earlier today. The only time it happened so far.

To look for a STD you must have a specific STD test.

From my understanding, you were diagnosed with Urinary Tract Infection rather STDs like Gonorrhea and Clamydia right?
Testing for white blood cells can tell the level of bacteria in urine but it's not a test for Gonorrhea and Clamydia.
I assume your doctor never suspected about Gonorrhea or Chlamydia. Normal level of white blood cells in your urine indicates that the bacteria in your urine is now at the normal level, which is a good news.
How often do you get discharge? You should talk and show your doctor about this.
