32 week scan to check placenta

Victoria

Hi Ladies, so at my anatomy scan they found that my placenta is lying low so have scheduled another scan at 32 weeks to check if it’s moved or not. Question is has anyone had this and how did the scan go? My OB told me they should check Fetal measurements and weight as well as giving us a good look at our little boy but I’ve read other women saying they only checked the placenta and that was it! Looking for some other people’s experiences. Going in 4 weeks!
