Full-term?

Laura • Second baby, One 4 year old girl and now a baby boy ☺️
What is considered safe zone for labor (full-term)? I've heard 37 weeks is but also heard 38-40. I'm 35 weeks and I'm not in a rush but I AM curious. When is it okay to have the baby? And has anyone had their baby at 37 weeks and had everything go well with a healthy baby?
