Do I tell him I’m pregnant today?

Ka

I really need some advice. Today 1/2/2019 is the one year anniversary of my fiancé’s brothers passing. He had a heart attack on 1/2/2018. I’ve had a feeling I was pregnant a few days now but just got my bfp today. Do I tell him today? I don’t want to take away his day for grieving for his brother. At the same time will he see it as a blessing? We have a 1 year old as well so I’m afraid he might be disappointed and feel overwhelmed as he is the only one working (comfortably)
