6 months pregnant and working

6 months pregnant - I am literally in pain every day.

My sciatic nerve is acting up daily now - to the point it can be excruciating to stand or sit for extended periods of time..

I also have pelvic pain that is the absolute worst if I sit for too long.

I work as a cashier - and although I have a chair, it’s not helping anymore because even sitting on a stool for 9 hours a day is killing me. I know I sound like a baby but I’m having a rough pregnancy... my mother and MIL both can’t believe all the issues I’m having.. to the point I just cry at night from the pain.. I don’t want to work anymore, but I have to for bills and etc. he works, but I don’t feel comfortable having him pay MY phone bill, and MY credit card bill until I take maternity leave... I’ve already mentioned to them I can’t work more than 1 day straight & I can only do 6 hours a day - yet they are making me receive an accommodation from the HR department which can take awhile, and I have to have my doctor fax paperwork to HR and wait for an approval (or disapproval)

I don’t know what to do. I just need about $200-$300 a month for myself to feel comfortable.. I want to work from home so badly but don’t know where to start.
