Wegovy - upping my dose

I took Wegovy with great success for 18 months losing 4 stone. I came off it for 6 months and regained 2 stone. I’m now back on it but 0.25mg has not even touched me. I took my last dose of this pen on Wednesday and am going up to 0.5mg on my next dose.

I am tempted to start the new pen early. If I take it tomorrow it will be just 4 days since I took my last (lower) dose. Has anyone done this and will I be OK or should I just be patient.

Thank you!
