C.P.
I had a full placenta previa, also diagnosed at 20 weeks. Although I was hopefull it would move, and my doctor was too, it never did. I ended up bleeding at 26 weeks - a lot of "old" blood, a giant clot. I ended up in the hospital for 6 days, since the timing of the bleed was too early for my son to be born. I got the steroid shots, in case he did come early, to help with lung development. Once released, I was put on bed rest unil I delivered. I was able to shower daily and go to the bathroom, but stayed in bed/couch for 9 weeks, until I bled actively, bright red, at 34 weeks. I had a c-sec and although my son was in the NICU for 11 days due to lung development, he is a big and happy 6 month old now. This was my first. No reason for the condition was given. You will have to abstain from sex or vaginal exams, since that can cause bleeding. It was tough since I A. very active, but I saw it as my job as a hen sitting on her little egg, and that helped when I got cabin fever. I hope your placenta does move, but will gladly answer any other questions you may have. Best wishes!
