Hcg levels.. Idk where to post..

Okay so I'm beyond upset. I went to the hospital because I've been cramping really bad and I just had 2 positive pregnancy tests 2 days ago. They took a urine and said it was negative so they decided to check my Hcg levels. He said it was a 20. I had my last period about September 9-13th ish. He said my levels were too low for me to be as pregnant as I should be based on my period. He said I most likely am having a miscarriage and I'll start bleeding soon. He's having me come in again in a few days to test again, but he said if it was a active pregnancy, it's probably and tubular due to the pains. I haven't stopped crying. I just moved out of state with my fiance and I'm still working on transferring my license and insurance over. I just don't know what to do. I'm 20 and I don't have anyone to talk to this about.
