I found out I am pregnant, but I started bleeding more than spotting. I went to the emergency room last night and they said it was unknow why I was bleeding but they think I'm only 3 weeks pregnant... however doc. Said my hcg level is 4000, not 400, 4000. I looked up what it should be around 3-4 weeks on web and says 300-400... why are mine SO EXREMELY HIGH?
