prescription acid reflux meds

Hi! Anyone in here on prescription acid reflux meds daily prior to getting pregnant? I was on lansoprazole put stopped taking it right around ovulation. I was worried about being on it for the first trimester. Well my stomach kills non stop and I know it's from the acid. I'm going to ask the pharmacist today when I go to pick up my husbands meds if it's safe to go back on it while pregnant. Anyone talked to a dr already and gotten the ok with it?
