So, my sons girlfriend just messaged me 5 mins ago to say she just tested positive with a lateral flow Covid test, she's booking a PCR for tomorrow. She was in my house tonight and been round us all. No idea what to do or what the guidelines are, cos they change that much! Does anyone know? I live with my husband, 3 sons and 2 daughters. Don't know if we can go to work/school tomorrow as don't want to potentially spread anything. We are in Scotland if that makes any difference
