Spotting.... Or old blood....

Ashly
Ok so today my husband tried a new toy. Its a sleeve he puts over his penis, not trying to be detailed but after intercourse he pulled it out and there was alot of blood. Could that be from penetration of my cervix? Or spotting or old blood from the last period? The last day on my last peroid was november 20th. I was supposed to recieve the 2 depo shot on the 12th of november but didnt because my hormone levels are out of wack, and they were making me very emotional, to the point of not even functional. Could it be bleeding from coming off the depo or spotting or bleeding from penetration? I'm not sure howitcould be old blood, it was bright red and I'm always cleaning down there in fear of getting a uti, i had utis while i was pregnant with my daughter and haven't had one since 2nd trimester. I stay clean, i am really confused. Do you think i could concieve so soon off the depo? Has any one else had this happen before? I am really confused... Help. Thanks in advance.
