Sooo much pain??

Brittnie • I`m 17, junior.
Ok so I had sex with my boyfriend Monday. And ever since then I have been bleeding like I'm on my period (I'm on the depo shot so I don't have periods or bleed anymore) nd I am (as we speak) in bed, with excruciating pain in my lower abdomin I believe that I can feel my overies swollen. Does anyone have any idea what's going on?
