This happens to me once in a blue moon. If imessage is not available it will go through as a regular text (if thats what you've enabled your phone to do).
There's not much you can do if you do not send the message a 2nd time.

If the message was critically important, I would have sent it a second time. If you were/are actually worried about the message not being sent, I would have called the recipient to confirm or communicated the important matter.
