Hi, I was wondering if anyone had been diagnosed (if that's the right word) with placenta praevia? At my 20 week scan they said my placenta was "directly over the birth canal" and my mw confirmed last night that I have placenta praevia. I have another scan at 32 weeks to see if it has moved, but everyone seemed very impressed with just how low it is

. Apparently on the 1-4 scale, it's a 4.
My mw has told me, worst case scenario is that I will be admitted to hospital after the 32 week scan for bedrest.
Has anyone had this? Did your placenta move? Did you have to have the bedrest? It would be great to hear some other people's experiences.
Thanks
