Save the date vs wedding invitations?

We’re getting married in 5 months. We haven’t announced the date we’re going to marry officially. But it’s a small wedding (20 people) and I was wondering , do we still need to send out our “save the date” cards? Or can we just hand out our wedding invitation cards instead, it’ll be our main family like parents, siblings and grandparents. We’re having a small wedding at a wedding chapel/court room ! ❤️💍👰🏻🤵🏼💍❤️


And a month after our wedding. We’re having a celebration with the rest of the family, which we’ll send another invitation but a “You’re Invited!” Card.
