Apple ID /ph. no. being used for Facetime/iMessage.

[NorthStar]

Today when I booted up my 2016 Macbook Pro, I was very surprised to find this iMessage: "Your Apple ID and phone number are now being used for iMessage and Facetime on a new iPhone. If you recently signed into iPhone you can ignore this notification."
I do not have a new iPhone, and the last time I signed into my iPhone 5s (which I have been using everyday for the past 2 years) was at least a week ago, and I have no idea what I should do.
This message is also on my iPad's iMessages, but the message is not on my iPhone 5s.
Any suggestions are appreciated.

Hello and welcome,

It is probably just a delayed message. If you double-check and see that all of your Apple devices are signed in with the same Apple ID, you're good.

Cory, a Big Thank You !!! for your help. I checked all my Apple devices and all are signed in with the same Apple ID, so I should be good.
