Stuck.

My husband is really worried about me being pregnant. He just got a call back to a job that pays well. Im doing CNA classes that only last for 12weeks and then i can start working. we are behind on rent right now and he is worried that we won't be able to provide for the baby. I dont know what to do or say to him to make it better. should i take the plan b? Or is there something I can say to him to make it better?
