Every child is a blessing, and as such no child is a mistake. Every child is unique and special in there own way, but when it comes on to a relationship, having a child can change everything.
I don't know if you realize this as yet, but once a couple have a child together, they can no longer put their relationship first, at least not while they've got a helpless newborn to care for.
Having a child can slow parents down (especially a woman), so that is why it is important for us as young and old people to plan our future.
If you cannot take care of yourself and you're still depending on your parents, how will you be able to take care of a child?
