Question and seeking answers...

Hi everyone.  I started eating keto Nov 1 and have been faithful with eating correctly since.  So far, I lost 9 lbs which occurred the first two weeks.  Since then I have stalled, not losing anything.  I log everything I eat and obsessed with making sure that my macros are correct.  My breath meter ranges anywhere from 5.5 to 9.95 which reflects  that I am in the medical watch zone.  I exercise and drink water.  So what am I doing wrong?  Measurements have stayed the same too.  Any advise would be appreciated.
