Symptoms or lack there of?

I am over 6 weeks now and have yet to get any true symptoms.  I am more tired than usual, but not exhausted and find that as long as I eat the nausea doesn't get too bad.  I do have a lot of cramping a stretching sensations, but that is the extent of it. Could this mean my hormones are low and I have a higher risk of miscarriage?  Just a first time momma trying not to worry...trying and failing.
