I need a couple questions answered

Hey ladies i need some advice on what to do. Im 6wks pregnant as of today, but im bleeding and have been for a couple days. I went to the hospital on Thursday and the dr said that my cervix is still closed. I also told him that i passed some kind of clot but it didnt look like a baby. They checked my blood and said my levels were fine , but to come back in and recheck my levels. Im so scared if i lost the baby. What do i do?
