My sister in law was told that she had little flecks like that and that it was because she was very dehydrated. And if she didn't start drinking more that she could end up with kidney stones.
That happened to me once when I wasn't pregnant when I went to the doctor they told me it was a bladder infection and just prescribed me some antibiotics!
I haven't been drinking as much water as I should.
Do you drink around 8 glasses of water a day? If you are dehydrated you can start peeing little white flakes. I have done that before when dehydrated. Drink more water and see if it goes away in a day or two.
That all I'm hoping it is. It kinda floats and is some what stringy, kinda like when toilet paper is left in the toilet too long. Sorry tmi.
It's probably just discharge in your urine. No worries hun :) very normal
