If you do have an imminent miscarriage, I am sorry to say that there isn't anything they can do at 9-10 weeks. If you'd prefer not to go to the ER, and you're not bleeding heavily, you are just as well waiting to see your OB -GYN tomorrow.
I've had three miscarriages and the first two were before the 10 week mark. The symptoms are very similar, but there are other reasons for bleeding during pregnancy.
My mom had something called a sub-chorionic bleed during most of her pregnancy with my brother...didn't even know she was pregnant for nearly three months.
My thoughts are with you. This can be a very hard thing to face even though it is more common than we often hear about. Take some time to grieve and gather your thoughts...and then try again.
