Bleeding during pregnancy?

Not sure if this is a controversy but I need advice. Found out last tuesday I was pg. Started bleeding heavy thursday. Had hcg #s done and went from 20-23. Ultrasound couldn't find anything so we assume everything passed. Just had #s done and they tripled to 150. Meanwhile I feel like abdolute crap! (Pregnancy symptoms still) gonna test them again thursday and if they double I might need an ultrasound. Has anyone ecperienced this before? Pg or not pg??
