I've had it from last Tuesday, but the positive line very faint this morning. I'd the most hateful headache with all the usual flu type symptoms and I've lost my taste, but nothing like your friend. This is my first time getting it and hearing different stories have been really worried catching it, but with different variants you don't know what you will get. I've friends, the whole family really sick with it and the father is fainting when he gets out of bed.
I was being careful, wearing my mask, washing hands, etc, but the bloomin thing still got me. I'm isolating, I'll do a test tomorrow and after today's result I think it will be negative, well I hope.
