How do you know?

Jordan
How did you know you were finally ready to start trying to conceive? I currently have baby fever through the roof. Both my cousins are 20 and pregnant right now, they seem really excited without a fear in the world. 
I'm 24 have a great husband and setup but so much fear runs through me when actually talking about trying and planning our pregnancy. I'm scared I'm too young, that my life will never be the same, that I won't be able to have fun anymore or that I haven't experienced enough yet. Then I look at my cousins and they already have such a strong bond with their unborn babies, they are excited, glowing and so happy!
I know fear is normal because I would be a first time mom but is there an actual time where you feel ready? I'm really confused..
