Low lying placenta?

Danielle
Just got the call that my placenta is low lying. It's 1.65cm from my cervix. I didn't have this with my last pregnancy. 
Does any have experiences with this? They didn't give me any restrictions, just said they'd do a follow up scan at 32 weeks and if it hadn't resolved itself they wouldn't let me labor and I would have to schedule a C section. 
Thanks ladies! I'm due 11/28 with a little girl!
