Am I or ????

Kerisha • Been off depo since July 2013 sooo TTC #1 since April 2014 :) :) excited!!
Has someone had this problem? I've had all pregnant syptoms and been cramping. I've been spot last week. This week I've bled twice that was it. My last period was Aug 28-Sept 4. Can someone tell me if I could be pregnant or what's wrong with me? Thank you!!!
