Covid positive. We would get negative?

Dear Docs.. me and my mom came into close contact with a covid+ve person without our knowledge. After 2 days we both got symptoms.. and being unaware that it is covid we went to general physician and he gave us injections and tabs. We got well within 2 days. But we thought of taking a test, and took it on 30th August. Our test results came positive yesterday. Even before then we wore masks in our household . Now we isolated ourselves in a room on the roof top and we have these symptoms only. 1.cough with phlegm (pale yellow) 2.mild headache at times 3.loss of taste and smell Apart from these we don't have any symptoms. Have no fever from past 3 days. All that is itching us is the Cough. Per hour 10 times we r having. When can we take another tets so we would get negative??? Also sir/madam - kindly suggest anything that will ease our cough and also we get negative soon. Thank you for your valuable advices . 🙏
