Rib and back pain

Currently on 2nd trimester suddenly have this pain under the rib all the way to the back!! 😩😩 it’s on the right side. Went to A&E KKH checked everything is normal, doc suspect either gallbladder or muscle ligament pain so need to stay a night to do further check in the morning. Found nothing from gallbladder result so likely is the muscle ligament pain. But it is so so so painful until cant sit and walk, any mummy experience the same??
