Placenta in the front of baby

Dena
Does anyone else have their placenta in the front of their uterus?? 
Apparently at my ultra sound today I found out my placenta was in front and the baby was in back so it's harder to feel the kicks.
I'm 17 weeks today and am feeling flutters though so I'm not sure if it's affecting that much.
Anyone else have this and when did you start feeling actually kicks or flutters?
