Everybody has a plan for their own lives, But God, He has His own for us. 
I used to have day dreams before, on what its like to be a mother. I was 19 at that time when i keep on telling myself that when i reached the age of 25 i wanna be a mother, and so God hear me. 
On our on perspectives, it is not the perfect time to have a child at a very young age. But God will do give what we really needed. God is more of giving the things we needed not what we only wanted.
