I had three episodes of hematuria, had a number of tests everything came normal but still have problems?

Hi. I’m a 36-year old male. Around April this year, I had three episodes of hematuria. Scared, I went to a nephrologist & then another urologist. They conducted a number of tests on me including urinalysis, urine culture, X-ray and USG of KUB, phase contrast microscopy, lever and kidney function tests and a range of other blood tests. Almost everything came normal and the phase contrast microscopy found that the blood was coming from lower urinary tract. The doctors did not find any stones, lesions or tumors during the USG.

One morning in August, I passed a nearly 2mm stone through my urine. The urologist says I do not need to be scared anymore.

But I have a few issues of concern:

1) Ever since, right after the hematuria episodes, at times, when I strain to pass a stool, drops of whitish semen-like substance comes out of my penis. In order to tackle this situation, I stopped straining at least a week back and it had nearly stopped. But over the past two days, I have noticed on two occasions, a small jelly-like transparent substance come out after I finish peeing. It usually sticks to the bowl and when I drop water on it, it rolls off into the water and sinks. Is this something to worry about?
FYI: My wife is pregnant. And I haven’t had sex or masturbated since September this year.

2) Often when I am sitting down, I feel a slight burning sensation near the head of my penis. Also, at times, when I finish urinating, I walk a few steps and then sit on the commode for the last few drops to come out. Over the last few months, frequently, the last few drops have been light yellow. Is this something to worry about?

I had asked about these things to my urologist. But he seems rather indifferent.

It would be great if you can let me know.

Thanks
