Subchorionic Hemorrhage...

I'm currently 19 weeks & 4 days, i went to my appointment today hoping for good news. i wasn't expecting to hear those words come out of my doctors mouth, again. This is the second one i have had just with this pregnancy. The first one they found on my first ultrasound which was when i was around 5-6 weeks. That one cleared up on its own, but they dont know if this one is the same one or a new one that has formed. they said its bigger then the first time. I am now being sent to a high risk obgyn and I'll be having more u/s and appointments because they are afraid i will have him too early... Has anyone else experienced this? If so what was the outcome?
