30 weeks searching for a new OBGYN help

So im 30 weeks went to see my obgyn due to urinary tract symptoms, before I arrived I received a call from his office stating he was out on emergency and not sure if he's returning , well I was told to still come in to have my urine tested , once I got there sitting in the lobby I over heard the front desk staff state oh If that's MS Miller calling  I don't wanna talk to her at all not realizing I was in the lobby  , I was shocked and made a big fuss about her comment!! Now I don't feel comfortable being  seen in that office especially after hearing her statement the office manager reassured me she was very sorry
