A couple questions.
Why do you want to get pregnant before you are married, since you have your wedding planned next year? Why are you not willing to wait one year until you are married to have a baby?
Second question, do you sense your fiance ever wants to be a dad? This is a HUGE question.
This is the man you are going to marry and spend the rest of your life with, if everything works out.
