Hi Irene. I meet with my supervisors every 2 to 3 weeks. We decide the next meeting when we meet up and discuss what needs to be done for that meeting. I find it works really well and it gives me a structure to my work. The only negative side is that I tend to work to the short term objectives that were set for the meeting rather than thinking of the big picture. If you haven't already discussed meeting structure with your supervisor, I would try and have this conversation so you both know where you stand! Hope this helps!
