anterior versus posterior placenta?

How far along were you when you found out if the placenta(s) were anterior or posterior? I'm 10+1 and have an appt today and thought about asking but wasn't sure if it's way too early... I'm just curious and also know it can effect when you start to feel movement, hear heartbeats, etc. thanks ladies!!!
