Okay ladies i need y’all help

My bf and I had intercourse numerous of times 2 weeks ago. However my period came 4 days after.

But now we are both getting symptoms:

Sore throat

Raspy voices

Itchy skin (my bf)

We’ve both gone back to our usual routines and busy schedule and

We’ve both been tested and we’ve both been treated and been cleaned but

Do y’all think it could it be anything else or just a flu or fever?
