Loss: hurting & confused

My grandfather passed away yesterday. It was sudden but not unexpected as he was 96 years old... turning 97 in 2 weeks I planned to announce it on his birthday by having him dressed in a shirt that said "Great Grandpa Est. 2016." I had a great day with him on Saturday and spoke to him just 2 short hours before he passed away with dinner plans for us that evening. He was my happy place and my best friend. I am at peace with his passing but I am feeling regrets by not getting to tell him I am pregnant. . . He is the only person in the world I wanted to tell.

Also now with the funeral and seeing so many family members from out of town I am torn on if I should tell people now? It doesn't seem right to take the attention away from a celebration of his life. We haven't even told our immediate family. But life is so short and I don't want any more regrets. I AM CONFUSED?! Any suggestions
