I've been diagnosed with low lying placenta at my 20w scan. I've read through threads on here but wondered if anyone could give an idea of experiences in my particular circumstances. My children will be 21 months apart, first was delivered by ECS. I've read that a previous c-section reduces the chance of the placenta moving but I can't find anything that says how much of a reduction it is. Im also wondering if given the relatively short time since my last section will have an impact. For info my notes say 'placenta reaches internal os' so not covering but very close.
