Why is my pee so cloudy?

This has been going on for about a week now, I don't remember having cloudy pee before this. I've been urinating normally, nothing different, just urinating 3-4 times a day. I don't drink a lot of caffeine or alcohol, and I'm on birth control which helps my period cramps and acne.<br><br>It's cloudy for about 5-10 seconds before turning normal again, and it doesn't leave a residue or anything. I've been to the doctor for other things, but they never checked my pee cloudiness before. My blood work is normal.
