Missed Miscarriage

I'm 9w5d and this morning I was experiencing some bleeding. Dr. said my cervix was still closed which was great except for when he tried to find baby's hb on the ultrasound. He said machine was quite old and scheduled me for a formal ultrasound at 3:45pm. I haven't had symptoms for 2w when I had my last ultrasound. The baby was great, but now that I'm home cervix is open and bleeding heavy, cramps are quite intense and I'm passing clots. This baby wasn't expected, but we had so much love for him/her already. Prayers would be greatly appreciated.
