Should I call back for results of a job interview?

I had a job interview last Friday at a gym for the position of a receptionist. It went really well and I have to say it was one of the best interviews I have had because I usually become very nervous. The person that interviewed me even said that she enjoyed the interview and was impressed with my answers. while I was leaving she called me back and gave me the staff rota for July ( which I found very strange ) she said that I should take it to have a look at it she said that she was still interviewing next week so I should hear from her in the same week. Having the rota did make me feel hopeful, but unfortunately I haven't herd anything from her. I have to admit it has left me feeling quite disappointed, I'm very nervous about calling her to find out if I got the job or not it all seems very strange because the interview was a very positive experience. What would you do if you were in my situation ? thank you for your help.
