Do I need to up my dose?

I’ve been on semiglutide for 3 months and lost 22 lbs so far. The first month I was on .25 and then the last 2 months .5. I’m happy with the progress so far but the last 2 weeks I’ve only lost 1 lb. I feel like I may be plateauing already? I honestly don’t want to up my dose if not necessary. Thoughts?
