I haven't had my period for 2 months...Last time was March 2010.

Usually I have my period every month from Feb - October & Then I will have no period on November - Jan.
But right now...I have no period since my last one which is march 2010.
I took 2 pregnancy test this month & It both came out negative.
I don't think I am doing it wrong...But I am not too sure.

I spotted light blood once this month but that was it...People say that's usually a sign of pregnancy...

Could I Be Pregnant? Has anyone every had this happen to them? Please, Please Help?
