I had an internal sonogram at 7 weeks pregnant today, revealing a normal pregnancy, baby, sac and heartbeat. My OB noted a large area of "white" on the ultrasound, outside of the sac. She is referring me for a level 2 sonogram. She thought it might be scar tissue from my prior pregnancy. I had an interstitial ectopic 6 months ago, cleared up through two doses of MTX. 4 months ago, I had a sono done to make sure everything was "cleared up", and only a very small scar tissue in the interstitial region where the embryo had implanted remained. I wouldn't think this was what was showing up on her sono? Any ideas what the large white area COULD be? Thanks.
