Placenta praevia mommas?!

Amy • I am pregnant with identical twins :) , i have one healthy handsome young man that is three. I did miscarry in march as well i have pcos. I am followed by specialists only big change from midwives.
So I was told last week I have pp. I am pregnant w identical twins. The doctor tells me not to really worry as it is early and as my uterus grows there is chance it will move out of the way. I am 17 wks Fri and go for my full anatomy scan the 11th of dec. Is there any other momas out there with pp and could let me know how you are doing if its moved etc
