I didn't move on to the XL's until I was filling the L's within the first 5-10 min of pumping, but it's really up to you and how you feel about it. The size guide of the domes is for your starting size, not what size you are now since you have already been using the system. It's just not a good idea to start with the XL's if you are under a D cup. How long have you been using NB and the L domes?
