Should I go talk to my husband or give him a minute

I'm 2 weeks postpartum. It's been exhausting and I'm getting 0 sleep. It was my husband's turn with the baby. He was holding our daughter, then his phone rang. He answered it. Said "What?!" Had a terrified look on his face. Then a blank look. He hung up and handed the baby to me without a word and went into the bathroom to cry. I have no idea what's going on.
