So dh friends brought some Xmas presents around on Wednesday and we have found out the tested positive for Covid. They were outside and we just exchanged presents but I obviously picked up the presents and cloth bag and I didn’t wash hands after this. It has been over five days since exposure now . Bil has rapid tests and I have taken one today which came back negative. I have no symptoms. I am in a support bubble with my mum who is in her seventies. Do you think I would have a positive result by now and am safe to continue to see my mum
