I was told at my 20 week scan that I have a low lying posterior placenta. I'm being scanned again at 36 weeks and I'm seeing the consultant a week on Friday to discuss it. When I google 'low lying posterior placenta' (I know I shouldn't do it) they cross use the term with placenta previa which looks like it can be quite serious. It says that I should avoid heavy lifting, vacuuming, sex and running. A lot of them say that bed rest is necessary. I feel fine and haven't had any major bleeding. Surely if I was supposed to avoid any of these things the hospital would have mentioned it? I'm just concerned as I had a large postpartum hemorrhage when I had a 'normal delivery' with my son (I lost 2.5 litres/4.3 pints) and I've been told that if you have had it once then it increases your chances of it happening again. Any ideas?
