Bilobed Placenta?

Has anyone else had Bilobed Placenta?  I just found out at 20 week US that I have two placentas, one in front and one in the back of the sac. I really wanted to have my baby at a natural birthing center, but now its looking like I may have to go to the hospital and may even have to have a c-section.  I'm okay with that if it's necessary to keep me and baby safe. I'm just wondering if anyone else has had this experience and still had natural birth?
