Don't know if this will help you and I'm definitely NOT the losing weight will fix all your problems kind but...
I had high BP while I was TTC. I had started LC'ing to lose weight to help with the TTC issues and after I had lost about 10-15lbs, my BP was back to normal.
Probably not the same issues you have though because my BP was fine during pregnancy. It had started to go up a bit near the end but I delivered at 38 weeks and it never got out of hand before that point.
Sorry I don't think this helped much but that's the extent of my knowledge
