First Response early detection

Would these tests be ok to take 2 days before AF is due? It says they can detect pregnancy up to 6 days before period is due, so surely two days before would have a chance of showing? I’m due on my period on Tuesday/Wednesday but so far have no symptoms of it 🤞it usually comes and ruins all my hopes but staying hopeful for now!!

Or are even the early detection ones unreliable two days before?
