I hope it's just a fluke

I had my son at 35 via crash c section due to severe pre e, iugr, low fluid and hellp. It all officially started at 28 weeks but went un managed because my Drs were awful. I'll be 27 weeks this weekend and I've been having bad Braxton hicks lately. I just took my bp and it was 135/97. I'm really hoping it was just a fluke. It's been 115/70 until now. Ugh
