Pain Discomfort in Penis

Patient: Hello I am a male, and 29 years old, and pretty healthy in general. I have a burning sensation when I pee and I have a seen a small amount of creamy white discharge, there is also a little bit of discomfort from time to time in what I believe is my urethra. This has been going on for about a week in a half. I went to a clinic 2 days ago and had a urine test for a UTI and a STD test for Chlamydia and Gonorrhea; everything came up negative. There referred me to urologist but the soonest they have an available time is mid-February ;considering going to another clinic hospital in different town. So if this is a UTI, Gonorrhea and Chlamydia what else could it be?
