Depo Shot- Blood clot in period?

I was on the depo shot a few years back and other than weight gain and irregular periods I don't remember having any side effects. Well I went back on it two months ago and I started my first period since about three days ago. It's been abnormally light, I've hardly had any flow; and then at about one or two a.m. this morning I passed what I can only assume is a blood clot, about the size of quarter. I've never had a blood clot, but my Mom said it sounded like what she gets during some periods now that she's gotten older. Should I be concerned?

HI,
Depo shots are known to cause irregular and scanty bleeding. As long as this is a one off thing there is no need to worry. You can wait and watch for some time. If bleeding becomes excessive or there are more blood clots then it would be best to consult your Doctor.
Hope this helps.
