need advice

went to the er because I had a positive pregnancy test. and i started to bleed pretty moderatly. They confirmed that I am pregnant. but they don't know if I will miscarry or not because it's so early. has anyone been through this? they say that the bleeding can be normal, that's it's just to early to tell yet. I go to a follow up app Monday to do blood work to see if the hcg is going up still.. I really just need someone to talk to. my husband doesn't understand much of what's going on..
