How to decide if having a baby is right for you?

M
So... I'm 32 years old, married for 2 years. Hubby and I have been going back and forth if we want to have kids. We are both on the fence and still not 100%. Part of me wants to have a baby, but I'm not sure if it's just the pressure in the world to have one? Or if I really want to?
Also, this world has so many uncertainties... along with it being overpopulated. My hubby feels the same way too. 
We are not preventing, and if it happens it is meant to be. 
Anyone else have these feelings?
