Am I passing a stone or not?!

I'm so fed up with this shit, yesterday I woke up in the middle of the night with that sensation that I really really need to pee, but then I had to practically force myself to when I went to the bathroom. Didn't see or hear any stone, and I didn't even think I was passing one there since I had no kidney pain beforehand.

No, instead I had kidney pain afterwards. At around noon the same day, I was practically curled over myself for 2 hours while I went to the doctor. They said they can see grains on the ultrasound, but didn't define a size. Told me to take Diclofenac and some other meds ( including tamsolusin ). Interestingly, within 15 mins of taking the Diclofenac, it relieved me and it felt like everything had subsided. I'm convinced it wasn't the pain killer, it was too quick and way too effective.

Anyway, that was yesterday. TODAY, at 3am in the morning, I woke up to yet more renal colic. Took some diclofenac, numbed it a bit, but didn't go away for 2 hours. Then it subsided unexpectedly. I again have no idea if the drugs did something, or if the stone passed or got stuck again.

And now here I am towards the end of the day, on 4 hours of sleep, losing my mind because I feel like I need to piss but my bladder is 100% empty. I'm drinking water like it's going out of style, like almost 4 liters today. I am, as of this moment, pain free so far as my kidneys are concerned.
