I would not call- it can put the interviewer on the spot, and they may be too busy to comfortably answer you.
However, it is normal (and good practise) to send a thank you email or card soon after interview (usually within 24 hours, but it would be fine to send it now). In it, thank them for their time, mention a couple of your strong points again, say how keen you are to work there, and ask for their timeline.
