I lied to my midwife with DS1's birth.
: I felt driven to do so to both protect her and have the birth I wanted. My bag of waters started leaking about 48 hours before the birth and ruptured more about 36 hours before the birth. Hospital policy was delivery within 12-18 hours of rupture, no exceptions.
I do recognize that this might not have been the smartest or safest thing to do. There was no *obvious prolapse (and ultimately no prolapse at all) and I took no baths/allowed no cervical checks/was GBS neg at testing. I kept tabs on my temperature. I kept tabs on baby's movement and heartbeat while I "labored" (really, just waited for labor to start) at home before I went to the hospital.
Midwife FOUGHT to allow me to labor from 24 hours from when she thought my water broke (I padded the time from the "big" rupture about 12 hours - that was the information she was going on). I did not want her to get into trouble (she did anyhow, but not over this issue. She *gasp* allowed me to EAT in LABOR!). DS came 27 hours after what I told them was the rupture time, and luckily I went into actual labor those last two hours on my own. Ohh there were fights and stress with hospital "officials" the whole time!
Yes, it might not have turned out as well. I'd hope that I could have been the one to get into trouble and not her since she honestly didn't know (as it was CPS was threatened no less than 3 different times to us). And, FTR, I did not and would not ever lie to my homebirth midwife I used for DS2. She's the only HB CNM within about 3 hours and I was doing anything I could to protect her and her license!
