Bleeding and HCG Levels

Shawn
Hi all,
I think I am 4 weeks and 5 days pregnant today, 2/3. I had light bleeding last week after my very faint positive on 1/26 so my doctor ordered a blood test for yesterday. My HCG number came back in the 200s. Now I know every pregnancy is different but my doctor suggested I be guarded about the prospects of this being a viable pregnancy. Going back for more bloodwork tomorrow to see if things have doubled in 48 hours. Can't do anything but hope at this point. Does the 200s seem really low at this point?
