In iMessage, receive a bubble with no text in it?

I always text this person. NO SHE DID NOT SEND ME A SPACE TEXT. I saw it on her phone that she sent me a message but it just shows blank text on my IPhone. Shows only a bubble with no text. 10 POINTS

The message might've been too long for your phone to display, or it might've contained a whole bunch of pictures that your phone couldn't read.
