Bed wetting!! What the heck!

I've been through two other pregnancies with no problem. For the first time as an adult I wet the bed!! Omg! So embarrassing! Has anyone else had this happen? It might be because of my dreams. They are insanely vivid. I am afraid to go to bed now! Will this continue? I feel like setting an alarm to wake myself up every 2 hours just to make sure it doesn't happen again. Help!
