Switching jobs :/

Can't decide weather I wanna leave my job for another job. My boyfriends sister said she could get me in to the Bank. I currently work at McDonald's but I make more an hour at McDonald's then I would at the bank. But I would have steady hours and paid holidays and they give you time off for breastfeeding. I'm a couple days over 25 weeks pregnant. Would that effect me getting the job? Or should I wait to get it after I have my son. :(
