HIDA scan

So I worked ALL.WEEKEND. and thought I would just drop in to say hey!  Tomorrow I have a HIDA scan scheduled to look at my gallbladder.  I've been having some problems with it, so now we will find out for sure!

Honestly, I'm hoping it IS my gallbladder, that way I can have it taken out BEFORE I get pregnant and have to be stuck feeling miserable for 9-10 months.

Has anyone ever had a HIDA scan?  I've heard it's not very pleasant, to say the least.

Wish me luck!
