Hello...

I'm in my 26th week of pregnancy... i had my previous scan on 30th August. My report says that "the uterine artery PI is raised with unilateral notch." does that mean that there is any abnormality or any other complications... All other reports are normal.. I mean regarding my Blood Pressure, Diabetes and RBC... doctor has advised me take aspirin 150mg daily after food.

this is my first pregnancy.. kindly suggest me what it is related to.
