Hello, i am 24 years old i was on depo for 1yr. My last shot was in july 2013 and my next one should od been oct 2013 but i didnt get it 2 weeks after the missed oct date i started my cycle and had regular cycles since that time, i am now 10 days late (last period was dec 6th 2013) and have take 2 pregnancy test in the AM and both were Negitive(it was a sad moment because we so want to be pregnant) is there still a chance that i am and maybe there are still traces of depo in my system masking it? or im just not? PLEASE HELP WITH THIS
