HIDA Scan with CCK.. Wondering............

I had my HIDA SCAN with CCK yesterday.   The test lasted about 90 min.    I felt mild abdominal pain during the whole exam.  When my intestines didn't show, the RN gave me some water to stimulate the gallbladder.  He said I only 20 mins to go before my 2nd part so he gave me some water to help the  intestine show.   Finally my intestines showed.   Is it normal to give you water during lst part to help the gallbladder function?    I had 10 mins break.  Then I had dr. give me the CCK.  Around the end of CCK injection, I had funny taste in my mouth and a bit nauseated.  The 2nd part lasted about 30 mins and then the machine stopped.  I saw my gallbladder still showing as tiny little bulb.   I read some posts here.  They said the gallbladder should be emptied out in the end.  I still saw min in the end of exam.  I won't see my GI until next week.   The RN wouldn't give me any hint about my gallbladder.  I am just wondering if my gallbladder function right according to my experience.  Any input would be appreciated.  I just like to get some idea first during "waiting" period.  I hate waiting............. Thanks..
