Hello, about one month ago I received the first dosage of the Depo Provera shot, I got the shot one week after my period and within that week I had unprotected sex, but I am almost certain pregnancy is not a possibility. I experienced discharge for over a week, but I was forewarned that this a normal side effect of the shot and not to worry, so it never crossed my mind to inquire about it. However, what looked like vaginal tissue came out of my vagina this morning. It was around 3 inches long and an inch thick, and it looked like raw chicken ranging from dark red to whitish pink. I called my doctor and they have scheduled me for a pregnancy test to see if this was a miscarriage, do you know the likelihood of this actually being a miscarriage or what else this could be?
