This is so sad. 3 questions I cant help you at all with! I am sorry!

What I can give you is my BP on the lead up to Harrys birth.

125/80, 110/60, 120/80, 105/80 and then 120/75 two days before I had him. The first lot was over a week, and the last one 2 weeks later. It kinda yoyoed. Not sure if its much help, but.. worth sharing just in case.
