When are you no longer contagious after a cold?

I believe I caught a sickness from my dad around the 1st or 2nd. It is now the 11th and I would say I’m starting to get better. It is also a Wednesday. My friend suggested hanging out next Monday. Is 5 days time enough for me to no longer be sick or contagious? I warned her I might not be ready but she insisted that she has a good immune system because her and her family are always surrounded by dozens of people and they are all very athletic and nutritious people.
