Yep - agree about the envy part

I don't think low blood pressure is a problem unless you have side-effects from it... sluggishness, fainting & stuff, ya know? I know that throughout my pregnancy, my BP averaged 90/60 & I even clocked a few 90/55's. That's pretty low, but it didn't bother me any.
If YOU feel ok, then don't worry about it!! Low blood pressure is a good thing
