bleeding

So I went to the hospital not to long ago because I am 8 weeks pregnant and I was bleeding, the doctor told me that I have a blood clot between my uterus and placenta  the doctor said that if the bleeding continues I might be having a miscarriage it stopped the next day it started so from the 16th to the 17th and last night I seen that a little bit was coming out. I'm so scared!! Has anyone had the same thing happen to them?
