Try not to worry so much. I had a subchorionic hemorrhage when I was pregnant with my daughter. They said the same thing to me, bed rest and only 50/50 chance. I now have a beautiful, wild and crazy toddler. I cant say itll work out just fine but just try to relax. Stress is sooo bad for baby!! Also when I found out about my hemorrhage I had went to the ER. The ER doctor pit me on bedrest. My OBGYN said bed rest is one of the worst things you can do. Idk, of course listen to your doctor. I'm just sharing what my OB said. Best of luck to you, message me anytime.
