Did I gain 2 pounds in two days?

I was 169.6 on Saturday. I was in ketosis but decided to take a break for two days after a 30 lbs loss. Today I weighed 171.0.

These past two days i did not have over 50g of carbs, and kept my calories under 1500 i also still intaked 90+ oz of water.

Is this a side affect of leaving ketosis? Or maybe water retention? Even without being in ketosis, I should still be losing weight with this calorie defect

*side note I am not in the stage of water retention when it comes to my cycle nor has my sleeping habit changed*
