Hi, I have been on the depo shot (birth control) for a little less than a year now, my next shot was due this month but I didn't go and get it. I have since been experiencing light brown spotting and light bleeding. I have been showing lots of early signs of pregnancy such as morning sickness, sore breasts, and what appeared to be implantation bleeding. I am wondering if it is possible for me to be pregnant and still be experiencing this bleeding?
