At this stage in the game, and if your nipps arent sore, clicking is her way of coping with the flow...flow is obviously faster when you're full (so you notice this more in the AM), so when its a bit much for her she breaks the latch, hence the clicking sound.
So, in answer to your qu, no its not a problem if she's happy and you feel her latch is good. Your supply will settle down over time
