Should i seek another opinion?!?

So here I am 36 weeks with my 3rd and last daughter, I have been seeing the doc every week for the last 3 weeks for monitoring and ultra sound I have had a uti this whole pregnancy on and off and have been on antibiotics for the past 2 months which helps for a week then next week is nothing. I have so much pressure and back pain and have for the last week I asked my doctor if she was going to check my cervix for dialtaion and she told me no that even if i was 3 cm dilated it wouldn't make a difference because I'm scheduled for a repeat c section on the 6th, well the last 2 days I have had severe back pain chills and a fever now I am too scared to even say anything to my docs because I feel they think I'm just being a wimp
