Pregnancy blues

I miscarried last October, lost my little one at 8 weeks. My husband & I have been TTC since. Honestly, getting these negatives every month crushes our hopes. It was upsetting to hear him say that he’s upset every time we test & it’s not positive. He was talking about giving up. Ladies, I don’t want to give up but what can I do to change his mind? I’ve never seen my husband like this. We’re a blended family so we’ve been trying to have a baby of our own. What else can I do to increase my chances of getting pregnant ???
