I have been on the depo shot for 10 months. I immediately stopped having a period after the 1st shot, and have never spotted. Just recently started having unprotected sex, I am nauseous at least once a day, which is not a common thing thing for me at all. I am also spotting, and have sporadic cramps, which I know is normal on depo. I m assuming the only answer is take a urine pregnancy test?
