Congratulations on losing the weight!
What is your height? Is your BMI in normal, overweight, or obese range?
At Weight Watchers, as you lose weight, your calorie (points plus) limit is adjusted downward - you need fewer calories to move less weight for your size (BMI).
So, depending on your height - your BMI is determined with that in mind - you may be just maintaining. In which case, good for you! Maintaining is a challenge for most dieters.
If you still want to go forward and lose a few more pounds (or even more than a few), then you adjust your caloric intake. In a healthy way!
