Signs labor is near?

2nd baby, I was induced with my first. Don’t read if you get grossed out easy Past two days I’ve been SUPER nauseous. And today a bunch of diarrhea. Also I think my mucus plug came out. I was in labor & delivery last week due to contractions and she said I was 1cm dialed. She sent me home with a sleeping medicine to get some sleep bc I haven’t been able to lately (Ambien). Should I call my midwife? I have an appointment Monday so I will bring it up then if not.Send
