Ovulation or Implantation

Okay, so on Day 10, my BF came over and we started messing around after midnight (so you might consider this Day 11). We did NOT have sex because I'm planning on waiting until marriage.  However, he started to finger me, and then I got him off.  We cuddled in my twin bed until I decided that I wanted to actually sleep, and so I got up and slept on the couch at 2am. At 7, I got up and crawled back in bed with him. I got him off again, and then he started rubbing my clit with his left hand, but I told him that I wasn't awake enough for that and he stopped after about 30 seconds. Idk which hand he was holding the towel with when I got him off the second time. A couple of days later, I started feeling pain on my left side near my ovaries. The pain felt like cramps, but was a continuous pain from 3pm until I went to bed that night. Does anyone know if this could be ovulation cramps or implantation cramps? I've never had either and I'm one of those people who will always fear the worst until I know for sure.
