Hi, uterine artery
Doppler is done to predict the development of hypertension
Its not THE test for predicting hypertension, its sensitivity is low.
The increased resistance and diastolic notch, just says to be cautious and have a frequent check on your BP. Presently everything in your scan suggest baby is doing fine. You can relax and enjoy your pregnancy. Do have regular fetal kick count each day and if you have less than 10 fetal movements in a day you can contact you doctor immediately. All the best.
