Corona related question. Pls suggest!

Hi My b-i-l got fever on 18 may we isolated him and he tested positive on 21 Exactly after 4 days i.e on 22 may entire family got tested as me and my husband has lit bit of sore throat . The test was swab and nasal and the entire family tested negative We continued wearing mask and on 25 we again tested as my husband has also got fever It was from different lab and was fully automated lab and icmr approved Again test result came negative for rt-pcr My sore throat is completly fine but sense of smell has reduced.Rest no issues till now. Doctors are telling it can be viral as we tested at 4 and 7th day of coming in contact with infected person. What should we do now as going for rt-pcr again and again is not feasible Pls suggest
