Pissed Off At Doctor!

Hope
Had a pelvic exam today, done by the same doctor who had done all of my exams. She says I am 3cm and 65% effaced. Just 3 days prior, she had said I was 75%... how did I lose 10%?!? When I pointed this out, she said it was subjective. Sure, subjective if it was someone else doing the exam... she's the only one who has done my exams since 36 weeks. And she also said my due date was the 23rd when it's been the 21st this whole time... obviously 2 days isn't much of a difference, but if I have to be induced that makes me miserably pregnant that much longer. They're going to make me go until the 30th if baby first doesn't come on her own. I had to stop working already and I've basically become imobile. My feet and legs are so swollen, walking is excruciating. But apparently this is all normal...
I'm just over being pregnant, over going to doctor's, and over being helpless and unable to do things myself!
Sorry for the long rant, I'm just becoming very depressed!
