Inertia - Excuse my ingorance but what is AROM?
Artificial rupture of membranes. Breaking my waters.

I usually let them do it when I get to 8cms dialated because it does make it go quicker at the end. Such as with DD1, the only thing keeping me at 8cms was my membranes were in tact. As soon as they were ruptured it "let go" and went straight to 10cms. They ruptured them at 8pm and I had her at 8:06. Its part of my "birth plan" that they dont AROM unless I have "stalled at 8cms". With Lyta they decided 7cms was far enough and I closed back to 5cms. That was at midnight. I had her at 8:26am - 4 and a half hours after they decided I had stalled and told me to "get some sleep".
