So on Wednesday I was a bit tired and assumed it was just from being busy at work. Through the night I was shivery and sweaty and by morning had headaches. Due to having a temperature, I've ordered a home test (not well enough to drive for one). However we've got loads of snow so it's not been delivered today. Tomorrow is forecast to be same/worse as due to freeze overnight.
If I don't get the test before 3, I can't send back until Monday, which is 5 days after the symptoms started. Can I still take it then?
