Family Relationships

My mother has passed away 5 years ago and my dad didn't find someone again so far. I am currently in a great relationship and I get along well with my boyfriend mother. Since yesterday I have this emptiness feeling in me. I am happy but I have the feeling.

I am 21 and still have 1 and a half month of probation period of work left.

Will it be a wise decision to have my own child to fill the emptiness I have?
