Pelvic pain?

Has anyone had any pelvic pain? It's not severe, it feels more like a mild soreness but it's right where my ovaries would be almost. This started yesterday and it's been coming and going since then. I ended my period on the 17th and I've had unprotected sex since then also. I doubt I'm pregnant because the only day he came in me was the day after my period but I know there's always a possibility. We use the pull out method (We had a slip that day lol). I was wondering if any of you guys have experienced this and what was the outcome?
