High blood pressure

This morning when I took my blood pressure, it was higher than yesterday (136/76), and I even meditated before taking it to try to lower it :(  This is really scaring me.  I am so afraid that my blood pressure is going to get too high again and cause Brooke problems and even require me to deliver her early.  Because this is what happened with Brady, I am scared to death.  I am going to try changing my diet to low sodium and some other changes and I am praying that will help.  Please pray for me that I have the strength to stay positive and hopeful, so that I don't put a strain on Brooke, and please pray for Brooke that she remains healthy and is able to grow properly.
