Going crazy about misscarig

I am 6 weeks 4day and sins Thursday I have been bleeding I haven't had any clots come out till today, I just don't no what to expect I have never had this happen to me before I have went to the ER they check and my cervix is closed and I have another doctor appointment on Friday to check if baby has a heart beat or not but the waiting is making me go nuts I try letting my husband now what's going on but I feel like I am just nagging at him with this I feel so alone and like I can't talk to any 1 about this. Has any 1 had this same this happen just time is what's driving me crazy till Friday comes and they tell me if there is a heart beat or not.
