Replacing one baby with another, will not help your heartache. You are always going to wonder what your first child would have looked and acted like throughout years to come despite how many children you have.
My advice would be to seek some counseling before you try for another baby. You should spend some time talking with your boyfriend about whats happened and what you want for the future and be sure that another baby is what you both want because it is still a huge responsibility.
I hope everything goes well for you
