With my first baby (she's 4 1/2 now) my placenta "died" around 6 months into my pregnancy. They didn't catch it until I was 38 weeks and I was induced the night they found out because there was little to no fluid and she was dying as the doctor put it. After I had her the doctor told me I wouldn't have to worry about it happening with any of my future pregnancies because it was so rare and hardly reoccurs.
