My waters were broken for me. I did go into labour naturally but the MWs made a mistake & thought I was 6cm instead of 2cm. I had been at hospital for ages & I'd already had 2 doses of IV anti-biotics so they decided to break my waters to get things moving as my contractions had virtually stopped.
When they were broken I was 3/4cm & strong contractions came as soon as they were broken. I was progressing ok after this, managed to get to 7cm then everything stopped. I had an epidural & he was stuck so I think both of these things contributed to my slow dilation. I was put on the hormone drip to get things going, and I managed to get to 10cm eventually. My LO was side on & I apparently have a small pelvis so I think I would maybe have always needed the drip. He didn't engage until I was fully dilated & I had a foceps delivery as he was distressed by this point.
Forgot to say, I found it very strange getting my waters broken, they kept gushing out every time I had a contraction. I thought it would never end.
