HCG Levels: What should range be @ 13 DPO?

I went to my GP this past week because I was ill.  I also suspected I was pregnant so they did blood work to confirm.  Turns out I have strep and have a hcg level of 505 (estimated 13 days past ovulation).  

It just so happens that my daughter needed an e-ray last month and I was 5 days late so I went to have blood work done then too.  My hcg level then was 5 -- but I started to bleed heavily the day after they took blood so the doctor assumed I had miscarried early on.

My GP didn't seem to be concerned.  I called my OB/GYN's office, and they don't seem to be concerned either, as they seem to think I don't need an appointment until I'm 10 weeks.

Should I be worried?  I feel like either this level it too high (even for twins), or too low if is a pregnancy from last month (which I don't think is possible).  Six more weeks seems like a long time to wait...

every HCG is different....and as long as the dr says it is good trust them. i am PG and had a period and blood work. i am still PG. some women are low and some are high....it is not the HCG as much as the progesterone level that is important. if your body makes HCG then the progesterone will keep you PG. talk to you dr if you have any concerns....all seems fine to me.

I would have them check progesterone.  I would call the dr. and request this before the 10 wk period. I have had 2 miscarriages, the last one i believe was because of low progesterone.  My HCG levels were good (1700) at 7wks but i was bleeding.  I lost that one.  I am pregnant again and my progesterone levels were dropping so the dr. put me on progesterone supplement (vaginal cream - 200 mg 2 X day) - good luck
