Should I call?

At my appointment at 2pm (Thursday) I was told baby boy has little to no fluid left so I needed to be induced. Our hospital is over flooded with pregnant women at the moment. Any way, I was told the hospital would be calling me at night to come in for my induction because they needed to free some beds and stuff of course. It’s now 12:18am and I still haven’t received a call. should I call the hospital or should I just go to bed and call someone in the am?
