Hello dear,i understand your concern.In my opinion placenta praevia in early pregnancy might not be worrying thing.Because the placenta moves upwards in 90% of cases.But till that time you need to be careful like avoid lifting weights,intercourse,physical strain etc.Take strict bed rest.Regular ultrasound help in knowing the position of placenta.Persistence of placenta praevia might cause bleeding before delivery leading to anaemia in mother and fetal distress in the fetus.With optimum care compkications can be avoided.So relax.
