So, just some previous history.. I always had a regular period. I knew when its was going too come and end. Once a month for 7days every time.
​Got pregnant w/ my first child and got on the depo right away. Had it for two years. Recently I started to have my period again since I got off it ttc.
​I had my period twice for the month of January. Then I got a small period lasting 3 days the beginning of February  and was suppose to get my period again on feb.16 and got nothing yet. But I was spotting on feb.13-feb.15.
​Could it b possible that I'm pregnant?
