baby is doing well, everything is okay except...

I was told my placenta was low and although its nothing to worry about at this point of course it bothers me. She says it should move gradually but if it doesn't I'll have to have a c section. I'm booked in for another scan when I'm 36 weeks. Plus the midwife says if there's any bleeding then call in immediately. I'm just praying this doesn't occur. Anyone in the same boat? I didn't even get any cute photos today, but I'm happy to know baby is healthy though.
