Thanks for sharing ladies, I'm glad I found this thread too. I was told I had a low laying placenta with my first pregnancy at 20 weeks and by 28 weeks it had completely moved up to it's correct position. However with this pregnancy I had another scan at 32 weeks and it still hadn't moved enough, I saw my consultant at 36+4 weeks and she said that I'll have to have a c-section, whihc has now been booked, due to it being a partial placenta pravaeria (spelling?) I was asked a number of times if I'd lost any blood or had any discharge with tinges of blood etc but I haen't so she dind't make a big fuss of it just told me to rest now for the next 2 weeks.
I'm glad I've read this thread though because it's made me appreicate how serious it can actually be and as I'm not one for 'resting' I know I'm over doing things, I'm a cleanaholic and always with the vac and stretching up high or bending down low to get to the nooks and crannies, but after reading this I'll be careful and try to put my feet up instead.
