Can barely walk!

I'm having such bad pains...like saddle sore but constant and worse everyday.  No exaggeration, it's making it difficult to stand up straight and walk.  I haven't been examined since 35 weeks and I wasn't dilated but was 50% effaced.  Hoping when I go this Thursday that I've started diallating. I can't see how I can keep going like this all the way to May 2.  Anyone else dealing with the same thing?
