How to bring it up to husband


So, backstory: Ive had 2 losses, both at or around 12 weeks in a matter of 12 months. We lost our second in January.. on my husband's 31st bday. Of course it took its toll emotionally..physically.. mentally and even spiritually. We took a family trip this weekend and I kept seeing pregnant women and little babies. It made me realize that I am inclined to start trying again. My hisband has told me that he doesnt want to try again until next year. I dont know how to bring up my desires to try again. I know he is afraid and he has said that he is scared to go through another loss again. He has mentioned not being ready but we havent discussed it recently. I just do not know how to bring it up to him again so he knows I am open to it again.
