Hi I am 24 years old, this is my second pregnancy, my first baby is almost 2years old and that's normal delivery, for this pregnancy when is was done my NT scan at 12 weeks they said placenta is low lying, and now when I was done my anomaly scan at 20 weeks they said placenta is in the posterior upper segment grade 0. Is there any chances to come down again, orlese is that creates any problem at the time of my labor? I have chances for Normal delivery?
