Sent my bf to jail tonight.

I'm 4 weeks pregnant and I just sent my bf to jail. I've never even called the police on him before. He is very abusive to me but tonight my kids were home & heard everything from the room they were in. I'm so scared for what is going to happen on Monday when he gets out. . I want to be gone by then but how do I pack up a whole house in 2 Days not to mention even finding somewhere to go. . Shelter okay yeah but what after that? I have no money at all. Idk what to do and I don't want to be pregnant with his damn baby 😢😢😢😢😢😢😢😢😢😢😢😢
