My husband is being stoic

I am having a really hard time with how my husband is responding to my positive pregnancy test from this week. Last year I had a missed miscarriage, found out at 8.5 weeks, but had stopped around 6 half. A year before that I had 2 chemical pregnancies within 3 months of each other.

He's being very stoic and reserved be and it's hard staying mentally strong all day and not really getting support from him. On top of all this I am working in a busy office and am back there 40 hours a week - so I unfortunately don't get to be by myself but have to keep my composure all day.

Any advice?
