The Pill and blood pressure

Esther
I went to the doctor yesterday to get some birth control. I've just started seeing someone and I want to be extra careful. Anyways, I was super stressed about going so when the doctor took my blood pressure it was a little too high to go on the pill. 
She told me to take it at home, if it was low enough go and get the script filled (she gave me the script anyway).
Has anyone else has high blood pressure but still taken it? I'm nervous now even if it is okay at home.
