he's so hurt and I am too and I need advice

I was talking to my fiancé about my old pregnancy test and what I was going to do with it. I was going to toss it but Liam wants it when he gets home. It was my first positive from when I was pregnant. We lost the baby on September 3rd at 8 weeks. He's so hurt and I don't know how to comfort him. Any ideas of what I can say? How can we move forward. We loved our baby more than ourselves and to have lost it hurt us so badly.
