34 weeks making today my last day of work

So i havent been at my job long enough for any type of leave and i have tried.to make.it till i go into labor but lately its just too much. The stress, the 6 to 8 hours on my feet, it all just really started being too hard for me to do and as much as i hate not giving a two weeks notice tomorrow when.i go in to pick up my check i will.be turning in my shirts and badge. My paycheck was just extra money anyways so well be fine until i am able to get something else after the baby comes. I still feel really bad.doing this to my boss but at the same time she didnt mind scheduling me 7 days straight when she knew i was.gettigg uncomfortable.
