This could mean that you lost fat (you got smaller) and gained muscle (you got heavier). This would be a good thing. Added muscle increases your resting metabolism, making it easier to lose body fat.
Instead of relying solely on the weight scale (which cannot tell the difference between body fat and lean body mass), you may want to consider tracking your body fat percentage or some proxy, like waist circumference at navel level.
Also, water weight can cause fluctuations of up to five pounds or even more.
