Newbie Routine Not Working After A Year Break

So when I first did the newbie routine it was way back in 2021 and I saw and increase in length of .25 inches in 2 months. When I had to take a break my dick shrank back down to its original size. Now after doing the newbie routine again for 2 months I haven’t seen any change in my size as I’m still stuck at the original measurements even though I’m doing the routine the exact same way. Should I give it another month to see if anything changes or should I start looking into mixing things up?
