Gallbladder pain!!

Hello! Can anyone who’s experienced gallbladder issues please comment:( I’m 37 weeks and 5 days and I’ve been told I have “gallbladder disease” and my gallbladder has low sludge in it. I was at the hospital for the last two days being monitored and in severe pain and they suggested I get it removed after delivery. I’ve had no previous issues with it prior to being pregnant so I’m really unsure what to do. My diet wasn’t awful to begin with at all! But I would like to know everyones opinions and suggestions. Also if anyone has had theirs removed for whatever reason, pregnancy or not, what was it like after getting it removed? Did you have issues? Or if you kept your gallbladder after delivery did it go back to normal! Please comment!:(
