As I was reading the post--first thing I thought was b/p either too high or too low. Then you said 169/92--that is .H.I. Some pple start out with low b/p so when it goes hi it is extreme. I am normally 110/65--when they found mine high in pregnancy it was about exactly the same as yours. I dont remember how early in the pregnancy, but it only happened in my first pregnancy. They say 125/80 is perfect, but for me that is already going up!!!
They did put me on some kind of blood pressure pills, and my baby lost all his water, he was almost dry when he was born. This was 25 years ago, maybe they have found a b/p control pill that is not so dangerous for the baby, by now.
Good luck, and be careful.
