Husband’s reaction to rainbow pregnancy

So my husband and I had a big talk a few months ago. We had decided to be open to having another baby (not prevent pregnancy), but not worry about timing sex, OPKs, fertility lube, or stressing about TTC. Three months later, I’m pregnant (and a bit surprised because it took us a full year to get pregnant with my son). Last night I told my husband I was pregnant. I had expected some mixed emotions (I had cried tears of joy and fear after taking 3 tests and getting the same results), but he just seemed angry. His exact words were “are you freaking kidding me!” I know he’s still grieving our daughter (we lost her at 39 weeks), but I was hoping there would be at least a tiny shred of happiness. I’m just feeling so hurt by his reaction.
