low placenta at 32 weeks....

Hi! My placenta is only 1.3cm from my cervix at 32 weeks. They'd like it to be 2cm. i was given little info at the hospital other than there is a fair chance ill be looking at a section. I'm reading that it's possible that it would move but less likely at this stage. it doesn't have far to go really....so I'm still hopeful. I was planning a home birth that I'm guessing would be completely ruled out if it stays low. I'm not sure if there is wiggle room for a vaginal delivery or where my hospital will draw a line for that. A section wouldn't be the end of the world of course but I've four other children to manage once I get home so a speedy recovery would be so much better. Would anyone have experience to share?
