What should I do?

Just found out I’m pregnant! Anon in case someone recognizes me. But I work part-time and am in part-time college, and have a preschooler. With my hours, I won’t qualify for maternity leave, but I’ll get parental leave. Last pregnancy I took sick leave too as my sciatic was so bad I couldn’t walk and most of me was swollen. I’m not sure what to do this time, do I go back to work and pick up more shifts, which takes time away from my education? Do I just apply for a loan and do school when baby is born… Advice please!
