Sick & 9 months pregnant

I'm so miserable you guys I'm trying to fight through this cold. On top of working overtime to stack money because I don't get paid maternity leave ( new job) . I swear I have sleep deprivation I can't get comfortable at night to save my life and when I finally do I have to pee 😭! I have the most active 4 year old ever that demands all my attention wants he gets home from school. With me being a full time student I think I might just fall out !
