To put the UTI into perspective, if in two weeks you didn't even know you had it, it can't be a bad infection - usually they're either a pressing matter you simply can't ignore or they just clear up on their own. In my experience if you have a bad one, you know about it!

As a repeated UTI sufferer, I can tell you this is not always true. I have had multiple kidney infections that didnt have any symptoms other than frequent urination. As a pregnant person, I wouldn't have thought twice about this because I'm going all the time anyway. Untreated UTI's can quickly turn into more servious kidney infections.
The tests are usually done in office anyways, and if they do send them out, they do not take 2 weeks. I think the office is just slow and dropped the ball... I would probably be pissed as well. Who knows how long it could have gone untreated if she hadn't of called them.
