Pelvic pain?

Jane
So I have been on the pill now for about 2 years. About 9 months ago I decided to start skipping my placebo pills and jumping to the next pack to avoid a period. My doctor says it is completely healthy. Once you start to spot you're told to come off for a week to let your lining she'd, otherwise if you don't spot just keep on taking them how you are. SO here's my thing.. I have no spotting. But I just started noticing this last month that I have some pelvic pain. Usually its a sharp pain when I sneeze in my lower abdomen near both my hip bones. If I press down on my lower abdomen I feel a little pain where my ovaries are. They feel sore. Or maybe it's my kidneys/bladder? I can't tell.. it's definitely not my uterus because it's on both sides, not the center. Does anybody have this? Or know what it might be? I've also been on birth control for about 9 years, all different methods, and never experienced abdominal pain. If it was because I haven't let my uterus shed for a bit now, then wouldn't it feel like period cramps? This side/side pain is a bit different than that.
