What to do next??

Jessica
My husband and I are just beginning our adventure trying to conceive (2 months) - I have been having what I thought were symptoms of early pregnancy (fatigue, sore breasts, increased urination, nausea). I am 10+ days past when I was ovulating and three days late for my period - I have very light spotting, dark in color. I have taken two pregnancy tests - both were digital read, not lines, and both said negative.  
I am not sure what to do - take a different type of test? Wait to get my period? Have I done something wrong? It is all a little overwhelming and I don't really have anyone to ask - any help or advice is most greatly appreciated!
