Pregnant with my rainbow

I just found out last weekend that I'm pregnant again after losing my first baby when I was 25 weeks pregnant on January 3rd of this year. I'm so happy/nervous/anxious because I want so badly to have a healthy baby. I went to my OB yesterday and it was confirmed. I told my husband the day I took the at home pregnancy test and he came to the doctor with me yesterday. But he hasn't said anything about it. I'm not sure how he feels about me being pregnant again and I'm not sure how to start the conversation about it...any advice?
