Dentist Refusing to see me due to a cough.

I had scheduled a dentist appointment at this business. When i arrived i was required to fill in forms, standard procedure, and a part of the form was a COVID 19 section to tick off symptoms. I had ticked cough ONLY because it is related to my ashma, which i was newly diagnosed with. The Dr then refused to see me to take precaution as she is highly pregnant. Fair enough. I left and was told to reschedule. Called the next day to reschedule my appointment and was told that none of the Dentists will see me as they are taking precaution. I 100% understand the precaution taking but i am actually taken a back by this because i know my cough is ashma and sinus related. Also they are working with gloves and masks. I am angered by all of this. People cough for many different reasons and to turn me away because of 1 symptom related to COVID 19. It's pathetic.
