WMMC- I'm so sorry
Like you I also developed PE in my 2nd pregnancy, much to my great annoyance and disappointment (also like you I'd planned a VBAC, and actually had good support from my obstetric team).
2nd time round it developed much more slowly than the madness of my first PE experience, and we limped through to 36+2 weeks, although I was admitted for complete bedrest and monitoring for a week before that (was on a cocktail of BP meds at that point). When my BP stopped responding to the meds and crept gradually up even though I had no protein in my urine they decided not to risk the PE becoming any worse (last time it very quickly went into fill-blown HELLP syndrome and I was very ill with it) and arranged a c-section. The consultant didn't want to induce me even at 36 weeks and after the antenatal steroids for the baby's lung development because of the high risk of uterine rupture in her opinion from the induction drugs. If I'd been more "ripe" they may have considered a membrane sweep, but I was no where near ready.
I still feel huge disappointment at never having had a shot at even labour but that's life eh!
During the c-section my BP spiked and I showed signs of seizures and needed the magnesium sulphate treatment again so I know they acting at the right time, although it was very hard having another baby go into SCBU
I seriously hope they buy you some more time and wish you the very best for the baby's birth, however it happens.
I spent 10 days in post section and by that time DD made it out of SCBU so we came hom together- which had been one of my great hopes! The first couple of weeks were tough, not being able to drive from the CS and juggling a newborn & toddler, but that stage didn't last long and we were soon all up & about ok.
Good luck xxx
