Concerned:Bleeding after switching from Shot to Pill?

I am very concerned about my body I have been bleeding since the May 24 weekend. Its not heavy but you know its there, it bloodied my pants :( so luckily I washed them and it came out. I am worried, I bled once for a month before right when the depo was due but now I am in my 2nd week of birth control taking it everyday so I dont get this. Is this normal or not. Also I got banged by a large sized manhood, and its been sore and still bleeding, went to the hospital, and said Im fine, let it heal maybe it will help but it was before that. HELP!
