Can't tell

So I am a mom of a 3 year old and almost 2 year old. My husband and I had a miscarriage in March and it was devastating, and honestly a rough miscarriage. The only ones who new I was pregnant were my parents. During my pregnancy I didn't have anyone excited about my pregnancy and no one after to help me or talk to. We found out I am pregnant again and we couldn't be happier. But once again my husband doesn't want anyone to no. Having friends and family be excited to me makes me happy, and it is extremely stressful to keep it from people esp my parents. How do I get my husband to understand even if this ended bad it's ok for people to no about our pregnancy. Too me it is a life and what's wrong with having support
