I'm 8 weeks pregnant and had bloody diarrhea?

I wouldn't be concerned that it necessarily has to do with your pregnancy. It's defiantly not normal, but it was more likely some type of stomach virus. Defiantly wait to hear back from your doctor incase it's any type of serious gastrointestinal issue that your doctor may want further evaluated. I can't tell you exactly what's wrong, but I'd think it's safe to not relate it to your pregnancy. Good luck.
