Hi. I am 22 weeks pregnant. I had the anatomy scan at 19w3d and all looks to be normal except for marginal placenta praevia- posterior and Placenta grad 2 maturity. I am less worried about the praevia as i will wait to see if my expanding uterus moves it away from my cervix but I am concerned about having a grade 2 maturity level when I m not that far along. I am 36 years old, no diabetes, good blood pressure, never smoked, ever, no drugs, healthy, etc... 1st pregnancy. Would you be able to tell me what this means and how to stop it from maturing so quickly? Thank you
