Acid reflux so bad :/

Hi ladies so now that I’m pregnant my acid reflux got worse. I have phlegm and cough for any little thing like if I gag, if I eat something with a little bit of spice, it’s so bad! I have omeprazole on hand from a while ago but stopped taking it. I won’t be able to get ahold of my doctor til Monday. Is this safe to take ? Has anyone taken this while pregnant? I’m currently 14 weeks pregnant. Thank you in advance.
