Weird question...

This is kind of weird, but since yesterday the right side of my upper lip has been twitching (not continuously, just randomly through out the day). Anyways, I was just wondering if this has happened to anyone else? Is there a specific reason for it? It's quite annoying, lol. Also, I am 34 weeks pregnant, I don't know if that might have anything to do with it.
