Good evening everyone. I can't understand what's happening. In the evening, pains started in my lower back and stomach, about two hours later, after brushing my teeth, about half a cup of water came out of me ? without any smell, it's not urine because I went to the toilet a few minutes before that. The pain doesn't intensify, the interval is either the same or fluctuates. With previous periods of water, they didn't go away ?. I don't know what to think.
