Pelvic pain is a reported side effect of depo and it is difficult to know if that is the reason for yours. The reported pain is not associated with decreasing levels and could occur at any time. If it is due to the sex, chances are it will resolve on its own soon. If it continues, you should have it evaluated by your health care provider. Being checked for STDs is a good idea whenever you are sexually active but other conditions can also cause pain since you have so many organs in the abdomen - bowel, bladder, ovaries, uterus, etc. It would be impossible to guess without an exam.
