Low laying placenta? Concern?

BabyNumber2
I just read my ultrasound report online (released to me via mychart). It mentioned a low laying placenta. Of course I jump to the Internet and get mixed reviews. It's NOT placenta previa, and I have had no break off of any part of my placenta, I also haven't had any bleeding at all during my pregnancy. I had the scan at 17 weeks 3 days.
I liked being able to read the results, but at the same time I am concerned! I'm a worry wart anyways so this is the icing on the cake. 
I know that those things cant get released to your chart without the doctor reviewing them, and I have not received a phone call about restrictions or any concerns she may have. 
Anyone have a similar situation and can offer me some advice until I can call her tomorrow (REALLT didn't want to bother her on the weekend )
