I just had the same problem with my pregnancy (had c section 6 days ago) and had contractions forover 2 weeks and they only ddialated me to 1cm. They had to bring my c section forward incase my water broke -as buby was breech.
Sorry I cant help more.
I hope bubby hurrys up for you - its horrible being so exhausted :(
It started for me at 29w. 33W I went into the hospital and I was 3cm 50 effaced contractions 3 min apart. I was sent to labor and delivery.. labor stopped at 5cm 90 effaced. I continued to have those same contractions with no progress until 36w and then they said enough was enough and induced me. It was a long month... but when they broke my water she was out within two hours
