Gallstones and frequent gallbladder attacks 31 weeks

Hi there, I'm new here and not sure if I'm posting in the correct area. I've been having frequent gallbladder attacks ( every second day) lasting approximately 20-30 minutes. Of course I've gone to the hospital and spoke to my doctor, and they do not want to operate u till after baby is born ( of course I understand). There is no specific trigger for the attacks, except when I find baby is sitting up/ kicking the area to irritate the gb. I really don't know how to stop the attacks. I have at least 7-8 weeks ( possible repeat c section) left which is a long time to suffer.

Hoping for some advice thank you.
