I am a 19 year old healthy male, I workout (lift) 3 days a week and I eat a mostly calculated 50% 30% 20% diet. This week has been weird, I found dark specks in my stool, which I took a pill that fixed it easily. But what accompanied dark specks in the stool was also bubbly/foamy urine. I am worried since this bubbly urine has been happening for 4 days, every time I go to the bathroom (the first two days of it had me constantly going to the bathroom).
