Am I Pregnant ? Any Advice

i was recently on the depo shot;;i stopped getting it. now im having symptoms of being pregnant;;i had some light pinkish spotting, bloating, tired, hungry, irritablility, frequent urination, cramping with no bleeding and back pain. i even had a pregnancy test done but was negative. so im wondering if these are symptoms from coming off then shot or am i really pregnant and took the test 2 early? any advice is better than none!! thanks :)
