no heartbeat?

Miranda
Okay so I went to the ER today because of bleeding and cramping. They did an ultrasound and said that I'm only 8 weeks (I think 9 weeks 4 days) and that they couldn't see the baby's heartbeat. But they wouldn't tell me I'm actually miscarrying so could it be something else? (I know I'm most likely losing the baby and it's killing me. But I want to hang on to the hope that I'm not as long as I can)
