FTM HELP!!

So I want to know if I’m over exaggerating. I’m the type of person that analyzes every situation and stress about EVERYTHING! I have a tremendous amount of pain in my hips and pelvic bone. I’m 31 weeks and doc said at my last app. That there wasn’t much she or I could do at this point since I’ve tried a belly band and athletic tape to sort of lift my uterus up, take Tylenol on a regular basis, and do a bit of light yoga and stretches for my hips but nothing relieves the pain. I’m a delivery driver for Pizza Hut and have recently noticed when I come home I’m in tears and it’s because of all the in and out from the car. I talked to my boss but he said I can’t do a day shift and not deliver. And night shifts are off the table since I take night classes. I’m wanting to see if my doctor can prescribe bed rest for work purposes only. I’m not allowed to take time off now and when the baby is born and I do not want to quit so I’m sort of stuck. So my questions are, do you think I’m doing the right thing for baby and I asking my doctor for this request and do you think I’m just being a baby about it or has anyone had to deal with this that can give some input or advice? Thank you so much! 😊😊
