<s>[INST] hi,i am 21 weeks pregnant but initially my doctors informed my placenta is low lying.it was around 1.1am anterior.but after my 20+6days Anomaly scan now my placental position is anterior high with the lower edge being 4cm away from the internal os.is it normal now? [/INST] Hello dear, I understand your concern. In my opinion your placental position is normal in position. Usual position of placenta is in the upper segment of uterus i.e., high. Presence of low-lying placenta in early pregnancy is a normal finding seen in a few women. As the pregnancy progresses the placenta position gradually moves up. If the placenta doesn't move up and remain in low position it is called low-lying placenta or placenta Pravda. When there is low-lying placenta there might be bleeding during the pregnancy leading to fetal distress. As your placenta has come to normal position you need not worry. Hope this helps. Best regards.... </s>
