How many days we can wait for delivery if placenta is grade3 n becoz 33weeks only the placenta came to grade 3..I m very much scared about my baby.. Humble request to answer my questions [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. A grade 3 placenta is a mature placenta. Your OB doctor is right to want you to repeat the ultra-sound scan sooner than the original due date. To wait longer would decrease the ability of the placenta to supply adequate nutrients to the fetus. Your description of the baby sounds like he/she is doing fine in your womb. Your OB doctor will decide whether you will need a C-section or not. I hope you deliver a healthy baby and enjoy your role as a new mother. Hope I have answered your query. If you have any further questions, I will be happy to help. </s>
