I am 36 years of age, 5'5" . I am 29 weeks pregnant and have been informed I have complete placenta previa which is not likely to move. When or do I take to bed? Or what are the recommendations to prepare myself? I have stopped working however I am 1 hour from my maternity hospital and would like to remain at homefor as long as possible. What are my chances to getting to 40 weeks for my c section?
