Who caught covid off who?

Anonymous
So I saw a therapist in her room at her office on Monday and we were both fine as we knew it. That same week on Wednesday I felt a little funny and my nose was blocked for an hour then it was fine. Next day I had extreme tiredness then Friday (so 4 days after contact) I had more covid symptoms

I informed my therapist who said she felt fine but that Saturday she had started to feel extreme tiredness so 5 days after our meeting and the day after that she had more symptoms

Is it possible to tell who got it from who?
