I just found out that I have UTI, and I've been waiting for my period since Jan. 11. Could that be a reason why I'm late?
I know it has been a while since you posted, but I was wondering how you are doing. Did you ever get the opportunity to return to your doctor? I am not a doctor and can't diagnose you, but Paul had a very good post above mine and gave probably the most common reason for a delayed period during a UTI--antibiotics/medications. I'm going to add a couple of extra links here to help you out:

Best of luck,
It may have some connection. Are you taking drugs for the UTI? That can cause a delay, as can stress and worry, and you may have some of that.
There is an article you may wish to read, written by Merely Me, a writer and community leader for this site, titled, Reasons Other Than Pregnancy for a Delayed Period.
She also wrote an article, What You Need to Know About a Urinary Tract Infection, that may be of help.
