I don't do WW points but log my cals in MyFitnessPal. I take a weekly view of calories eg because of my ToM and very cold weather I've overeaten a few days this weeks. It means I have two days of undereating left to undo the damage and get back on track. Could you eat less points tomorrow and Sunday ie the difference in the extra points you've eaten so far?
I'm on ww and have eaten all my points (healthy food, but with a couple of hot chocs thrown in). And now have some fruit strudel cooking and am looking forward to a comforting bowl of that for supper with cream out of the rest of my weekly points.
If DH clears off to potter in the garage, as is his habit, then I can get a bit of exercise in to soften the blow.
