May I join?? (kind of long)

I've been looking through these boards for the past few weeks but never left a message but I am hoping maybe I can get some insight if anyone has had the same issue and their outcome.

I am 25w2d now and on Thursday I had alot of bleeding with no pain out of the blue. I had been having a perfectly normal pregnancy until this. They kept me overnight, the bleeding subsided, gave me steroids shots for my baby's lungs, and sent me home on Friday night on complete bedrest. I was fine until Sunday morning when I woke and threw a huge orange sized clot and continued to bleed, went back to L&D where they monitored me for 12 hours and sent me home again on bedrest. This entire time my baby has been doing great, no dips in HR and moving and shaking all the time. I went the MD yesterday and he placed me on modified bedrest (I can do steps to the bathroom and shower). They said that I am having a marginal placental abruption and that I can begin to bleed at any time. I have none of the risk factors and have been feeling fine otherwise. Any insight? I am hoping they keep me on bedrest because I am so scared to do anything for fear I am going to bleed or go into labor and it is too soon for me to have my baby.
