So in July I got my first and only depo shot and I was suppose to get it again I October but I didn't. I got my period in November and then I December I got it again when I was suppose to which was the 10th but then 13 days later I got it again. I had unprotected sex on January 4th and again January 11th. Just now I got what appears to be my period I have some cramps. Is it possible I might get pregnant I'm so confused
