Maternity leave

When did you guys go on maternity leave because next week i planned on working my last week for maternity leave when im 38 weeks but this week im literally dragging . i dread going to work so much but my job doesn’t give me paid leave im really close to my set goal of money i wanted to be saved but i honestly know my body isn’t going to allow me to work a full week next week and i just feel so sad because i wanted a full check before my baby got here but i dont want to overwork myself .im literally in the last few weeks of my pregnancy so i know i need to put my health & the babies health first .what did you guys do about maternity leave if your job didn’t pay you for your leave ?
