HELP!?!pregnant with low HTC level...

I'm completely freaking out because I found out I was pregnant which was unplanned but not unwanted. I get my.lab results done and I call to get the results by my period I should be about 5 weeks.i ovulated 14 day ago.

my hcg level was only 188. I'm concerned and can't repeat the test u til Friday but that also means no results until Monday! I dont know if I should prepare for bad news or if this is a co.mon occurrence. PLEASE help ease my racing mind.
