Talk to General Physician on Cough Wont Stop

My father was Covid+ve and now fully recovered Allhumdulillah. I caught symptoms as I was taking care of him on July 2nd Thursday. I had a cough and fever between 99 to 100, the fever stayed for good 8 days and i dont have any fever from past 3 days. However the cough is irritating me a lot. I feel a lot better, I am working from home, walking for 30 minutes as well. But the cough gets really bad at night. I am taking Hydryllin twice a day, steam 3 times a day. But, I don’t think it’s helping. Can you help? My Spo2 saturation is between 100 to 97 mostly but sometime goes to 95 as well for a few seconds.
