OK its not that bad over the time you are stating unless you are trying to lose weight, in that case you are not watching what we are eating are we, remember to lose, 2 things are,1 self control, 2 breaking habits of our old eating pattern, if you are on a diet just stick to it or find a better one, other main things are no fast foods, cut out alcohol, cut out smoking, and just get out there and exercise, walk, jog and the gym, you can do a walk jog pattern and these are free the gym you pay for, ok.
Good Luck
Weight can fluctuate a few lbs and it's completely normal. Yours has only went up and down 4 lbs so I would say you're probably just fine.
