Hello ladies, anyone have this experience where you're walking to the bathroom and it feels like everything is pressing down? Like your bladder is super full and painful, barely reaching the toilet, and when you start trying to go, it doesn't come out easily, like you're squeezing to get the pee out. Also today I had one instance where I went to the bathroom for a small amount, but there were white flakes in my urine, like snow? Anyone else experiencing this? Please reply if you have!
