Blood pressure during C section?

Aubrey • Mama to 1 & baby #2 on the way

I had a consult with the anesthesiologist last week to discuss the risks of a c section since I have to have one ... one thing mentioned was that usually the spinal tap can make your blood pressure drop low. I already have pretty low BP so now I’m worried it’ll drop too low during surgery. Has anyone had this happen? What does happen if it drops too low during the C section?
