Your weight can fluctuate by a few pounds almost daily. There are many factors that can affect your weight such as menstrual cycles (up to 5 temporary pounds), salty meals, medications, increase in muscle mass, etc. Do not be discouraged is your weight goes up and down by a few pounds - this is pretty normal. Remember to also consider how your clothes fit, your energy level, your overall health, cholesterol levels, etc.
I will recommend you continue with your plan unless you experience a permanent weight gain - for more than 3 weeks. At that point you may decrease your calories by 200 calories until you find the calorie level that allows you to safely lose between 1 to 3 pounds per week. Also, try to change your work out routine as much as possible. Hope this helps.
