Horrible taste in mouth?

[Nowmum43]

Both my DD's have covid. For a few days now my mouth tastes vile and I feel really sick. I've been doing twice daily lateral flows which come back a definite negative.
Is it a sign of covid or am i just over thinking it?

Possibly. My mouth was awful when I had covid.
Get a PCR test. Tell them you have a temperature.

That’s how mine started and had it again (only 12 hours) when I had my first jab. Get a PCR just to be sure.
