34 Weeker Experience?

My daughter will be born at 34 weeks gestation via C-Section due to a rare condition called TRAP. Currently 32+4 and have in hospital 42 days. A TRAP twin pregnancy is where a passed twin continues to grow because she's pumping it blood which can cause her heart to strain and possibly fail. The mass is 20CM in diameter and it's miraculous she's made it this far and looks as good as she does. She was 52nd percentile at last growth scan 4 weeks ago and weight 2lb 9oz and having another tomorrow! 34+3 weeks is for sure and already have OR booked. Wanted to do natural and could because daughter is healthy enough (as of right now we're still watching for signs of heart failure) but the other is a mass of tissues that will probably rip my cervix open and I'll die before we get to an OR if I try. I wanted to know what your experience with stage in gestation? Long NICU stay short stay no stay? I feel like 34ish weeks is when it becomes really grey and just depending on a LOT of factors. Is that true? I know some who were there until due date and some who had no NICU at 34 weeks. What about you?
