What do I do?!?!

I'm 31 weeks pregnant, and ALL day, literally, A L L L L L L L L day, my left eye has been twitching. Is this normal???? What should I do? I've never had this. My eye has never twitched like this. My eye is twitching, my eyebrow, and it's just on one side, my left. It's starting to bug/worry me! 😣😭
