In brief: You are correct

Macrobid, long acting form of Nitrofurantoin macro-crystals is good at sterilizing urine ; treating uncomplicated bladder infections or antibacterial prophylaxis but does not achieve tissue levels needed to treat kidney infections.
Flank pain with UTI is a kidney infection until proven otherwise and require a bactericidal antibiotic with good tissue levels, cotact your dr asap to start treatment.

In brief: Call your doc now

As you may have a resisitent infection to the Macrobid which is not uncommon and u may be getting a kidney infection, if your doc doesn't call you back which he or she should then go to the er for evaluation and wnat to r/o a kidney stone also.

In brief: See your doc

Macrobid is fine for a simple, uncomplicated uti.
However, if the infection is spreading to your kidneys, then you need a different antibiotic. However, kidney pain (typically back pain) isn't sufficient to diagnose a kidney infection (pylonephritis) as you could simply be dehydrated. If you have back pain and a fever/chills, see your doc right away.
