Announcing rainbow!

So I’m hoping for my bfp in the next few days! And I was thinking of how to announce our rainbow to my hubby. As I’ve had previous mc I can have a scan at 6 weeks, so I’m thinking to wait until I have the early scan and make sure everything is okay before I tell him? It hits him so hard every time, I just want to be sure!

Do you think I should wait until the scan? Or tell him straight away? I’m so torn :(
