Hi I had been on the depo shot for two years. I had a period and the end of every shot for 2 weeks. My last depo shot ended on may 11 this shot I bleed for almost 4 weeks, the last 2 weeks were very light and mostly brown blood. I have been cramping for the last 2 weeks but no period and I started throwing up 2 days ago. Sometimes when I go to the bathroom I have this white cloudy discharge. Is it possible for me to be pregnant even though I have been on the depo for 2 yrs and just got off..
