I'm my second depo shot ,after taking lupron shot for 6months. I had a pap smear done that same day. on the 8/27/08. the first shot I spotted just a little bit. On 9/6/08 I went to the bathroom and toilet had blood , but no blood on my pad. that happen twice that day ,then stopped. now I went the bathroom again today a few minutes ago, and the same thing happen again. Could it be coming from my bladder,or could it be cyst, that have burst.
