How long did you stay at each level?

I know this question depends a lot on goals and personal experiences but would love to hear about when people knew it was time to go up to the next dose. For context I'm taking Wegovy for weight management and I stayed at the first dose for 1 month and I've been at the second level for 3 months. I'm still dropping weight but very slowly. How did you know it was time to go up again?
