I would fudge the dates, certainly. They're taking away your options and risking the health of you and your baby based on ideas not even based in science or evidence, so fudging a few days for the safety of you and your child is not bad at all, IMO (and if I were you I would fudge by at least a week simply knowing that babies in my family come at 41w at the very earliest and DS was 41w4d). In fact, my MW got a different date from me for this pregnancy (by 4 days - and she just used her little wheel thing from my LMP, so I probably just counted a little off since I was counting forward 40 weeks
) and she said why argue? It's a good thing - a bit more of a cushion!
Two things, though. For the high blood pressure there are things you can do. What worked for me was major increase in protein intake (80+ grams a day - but watch out for sugar in protein bars and stuff - it's very counterproductive!), more exercise, scullcap or hopps tincture (I took scullcap) and garlic. More importantly, they CANNOT FORCE YOU to have a repeat cesarean. You can keep rescheduling the date or simply refuse, and then just go in while you're in labour and refuse a cesarean. Easier said than done, but you do NOT have to consent to another RCS!
Good luck, mama!!!
