Frequent urination only while trying to fall asleep.

My question is about a urinary tract issue. While trying to fall asleep(The period at which I lay down to attempt to sleep to the point I actually fall asleep, usually 1 - 3 hours) I have to frequently urinate, between every 10 - 30 minutes. The amount of urine is small each time. Once I fall asleep, and during the day, I have no problem going 2 - 4 hours between urination, and often sleep a full 8 hours without awakening to urinate. I'm currently without a doctor and would like to know if I should be attempting to see a clinic about this issue.
I'm male, 29 years old. Roughly 6' 1" tall, and weigh 228 pounds. I have no serious health issues that I have been previously diagnosed with.
