Job prolems

So ive recently moved and i was working a job that recently have cut my hrs. Refuses to give me anymore and i had to do something so i could pay the bills. I got a call today that i got a job closer to home and pay is a little better but they do not know im pregnant... my biggest fear is that they are not gonna want me because im gonna need time off for the baby but i wanna continue to work there afterwards too. How do i got about telling them? Im just really nervous they are gonna turn me away. Any advice? Im 30weeks
