Uterine artery tracing

Karen • Believer. Wife. Mama bear. RN.
So- I'm seriously committed to staying out of the hospital if at all possible for the birth of our first child but I was just told that during my anatomy scan they saw a notch in my uterine artery tracing that COULD point to a chance of preeclampsia and risk for IUGR. Then I was told by that dr that it could be something- could be no big deal. So I totally chilled for a bit...and now it's kinda eating away at my psyche as I am terrified of the hospital and a c-section. He's measuring right on track and I've had no symptoms except headaches in the beginning that I finally realized were caffeine withdrawal...
Anyway my question is has anyone else been told this? Anyone with preeclampsia catch it this early with something like this?
