My bfp just may end in a mc..

I'm so scared and freaked out... I'm 6 weeks and 5 days, I went to the ER last night because I was experiencing heavy cramping and started bleeding.. I thought I was having a miscarriage so I drove myself to the hospital. Results came back and said the baby is still there, but they can't guarantee I won't miss carry... 😢😭

I was told I have a subchorionic hematoma It was bothering me so I looked it up, its a blood clot that forms. These clots can be serious because they might grow large, and thus cause the placenta to separate from the uterine wall. This is my first baby and I'm scared beyond belief, any advice ladies!? 😓
