Symptoms?

A couple weeks ago, SO & I TTC & 4 days after I woke up in the middle of the night with a cramp in my lower tummy that kept me awake for about 10 mins. Woke up the next morning feeling fine. Then two days later I had light spotting. Now I feel a little warmer than usual but hubby says I don't feel warm. He also made the comment that I look darker than usual. My sides & tummy also itch. Should I test? Is it too early? I don't want to get my hopes up & not see a BFP.
