I didn’t get a stimulus check. What can I do?

I qualify for the check and so does my husband. I worked in 2019 but not 2018. We had our 2019 taxes done like end of March early April. I was suppose to get it. We filed jointly but the check came and it’s only $1,200 for my husband. This isn’t fair. I’m suppose to get a check too. Is there anything I can do?
