work advice ..

Hannah
So I'm 18 and I work part time at a restaurant and I am 32 weeks today. I had planned on working all the way up till my due date which is Aug 10th but work is starting to become much harder on me .. I have to wear long sleeve black shirts and dress pants it's pushing 90 outside everyday and I stay in the kitchen at work. Some weeks I work everyday and others I work only 4 days there's no set schedule and if I ask to be worked every other day it never happens .. I'd like the money but my boyfriend can support us on his own. Should I go ahead and quit or keep going ?
