TTC: How soon should I tell hubby?

Hi everyone! My husband and I are ttc for our first child. We unfortunately had a miscarriage at 6 weeks in June and it was heartbreaking! I was soooo excited and I created a scavenger hunt to tell him I was prego. He was so happy! To go through the miscarriage process was really painful. We needed healing and I went through counseling. We are finally trying again and this time I told him I wanted to wait before I tell him. Like I want to wait until I’m like 10 weeks. (Not too bad right??) He wants me to tell him right away when I’m BFP. I understand that I need to stay positive and I am. I am praying that all goes well. However, I really do not want to break his heart again if I tell him too soon. Any advice? How long did you all wait to share the news with your significant other? Thanks!
