Bad cough, pain when breathing and 17 weeks pregnant

I've been to several doctors and they all say theres nothing they can do cause I'm pregnant but that was when it was just a cough. Now it's really tight and hurts when I cough or breathe deeply and when I stand up I have pains in my lower abdomen from coughing so hard. I dont know what to do. I'd go back to walk in once again but its closed.
