Relax! It is perfectly normal to go through some ups and downs. Your body is probably still shedding fat, but that dratted scale doesn't account for variations in the weight of food you eat, variations around TOM (time of the month), water weight fluctuations, gain in muscle, slight constipation... the extra two pounds can't really be accounted for. It could be anything. Just keep up the good work, and don't forget the merits of the good ol' measuring tape.
