Gallstone or gastric pain?

18 weeks into pregnancy and started developing this pain in the right upper abdomen area ,below the breast bone that is always there. Pain when palpated, pain intensified after a meal (especially so when I get bloated very badly) and sharp when I lie down on my right to rest at night. Antacids prescribed but not helping the most, I have a hunch it’s gallstones… but what can be done during this period of time being pregnant?#pleasehelp #firstmom #firstbaby
