Hi and welcome to HCM,thank you for your query. No,these 2 procedures cant verify some liver or pancreatic diseases. You need to do ct scan or some certain laboratory findings to evaluate this. Your symptoms suggest stomach issue but also it can be caused by bowel disorder or pregnancy. So you may need colonoscopy too. Since you are pregnant ,you should not do ct scan and mri would be better option so consult your doctor about it. Wish you good health. Regards.
