I'm 27w3d and have been on bedrest for the last week due to a shortening cervix. I went in for a check up today and it turns out I lost 4 pounds since last week - how is that possible?? Doctor was concerned, but neither of us have any explanation for it. I've literally just been eating and laying for the last week. Has this happened to anyone? I'm still on modified bedrest and am trying to increase my calories, but I'm worried something is wrong.
