Dog Pooping and Peeing in House at Night?

I have a Bichon Poodle mix. She will be 6 years old in September. For the last 3 nights she has been pooping and peeing in our bedroom and the living room. I take her out before I go to bed. She used to hit the bed and whine when she had to go out. Now she just does the deed. She doesn't do it in the day time when we're gone for an hour or so. My husband and I are here all day long.
