suspicious text disappeared after clicking on it

I received a text notification from "my bank" stating that a credit was applied to my account. The sound of the notification was different that my normal notifications. I clicked on the notification and when I did that, it disappeared. I can't find it with my other texts either.

My question is how likely is it that it was sending me malware? I've changed my email and bank passwords, but should I do more? Reset my phone maybe?

Any suggestions?

Thanks!
