Apple Watch/iPhone X message app

I texted a non-Apple phone on my Apple Watch. The first time I sent it, it pended for a while, and then said “not delivered”. So, I typed out the message and sent it again. This time, the pending hasn’t stopped, and it’s been about an hour since it started. I tried turning my watch on and off, but it still says it’s pending. However, on my phone, both messages appear to have sent. Did the messages actually send if it says they did on my phone? I’m just confused because the texts were sent on my watch, which says the message is still pending. Helpppp.
