I been getting the depo shot for 6 months which means I have taken the shot 3 times and my 4th shot is due on December around the 20th. For about two weeks I have been light spotting brown and it only showed when I would clean myself which has happened to me before since the first time i got the shot, so I know that was normal, but now I been actually bleeding and its more, like a normal period, I even have to use pads and i been having bad cramps. Is that normal? By the way every time me and my boyfriend have sex he cums inside me.
