How often should/can I size up?

Just received my kit in the mail and am super excited! Just wondering how long I should wait in between sizes? Currently at 5mm, about 10 years ago my ears were at 20mm so I've found that I was able to get from 2mm to 5mm relatively quickly this time around (in about 2 weeks) Is this just a matter of seeing how my ears feel and react before I try sizing up again? Ngl, it's going to take a lot of self control to not go straight to 10mm.
