Hello,My name is Alexandra,I am 21 years old,and I'm 29 weeks pregnant.At 20 weeks ultrasound doctor told me my placenta seems to be posterior,and covering os.I ask her what that means and she said"well in this case we are talking about caesarean section",and then she told me have more rest don't work hard and any bleeding you may observe,please contact the hospital.That scared me a lot.I got a 32 weeks scan rebooked but i am going crazy thinking about what will happen.My question is:In some cases placenta is going back to normal at the end of the pregnancy?I don't have at this moment any bleeding and i did not have at all before
