I tested positive today and haven't seen any threads listing symptoms in order that they appear so thought this might be helpful if anyone else wants to share:
Day 1 - felt a bit weird all day, couldn't put my finger on why but I just felt 'off'.
Day 2 - woke up in early hours with a killer headache. Cough started around 9am checked temp which was 38.2 and felt shivery and cold. Slept from 3pm - 7pm. Cough seemed to be getting worse but temp subsided.
Day 3 (today) woke up with temp but subsided after taking paracetamol and not returned yet. Covid test at 9am. Cough easing a bit but still feel very fatigued. Positive result 11pm
Will keep updating as it progresses (though I'm hoping it doesn't get much worse)
