As per your sonogram report, the presentation has been mentioned as breech? or vertex? The placenta is no more praevia. Most often the placenta is lowlying in early pregnancy
but as the uterus
enlarges, it also moves up. You can have an accurate idea at about 34-36 weeks gestation because the placental position at that time is important. even the presentation now does not remain the same, it tends to change. As far as restrictions are concerned, it is always advisable to restrict intercourse and heavy activity in pregnancy. Please consult your doctor for further advice. Take care.
