Implantation?

It’s been 11 days since I had sex and I’m having these painful cramps in my ovaries more so on my right side but in both. Feels just like period cramping. And I have pressure in my lower back like I need to go #2 but I don’t. I’m not due for my period for another 2 weeks. Could this be implantation? :) I don’t want to get my hopes up lol. Just wondering if anyone else has had this happen and ended up being pregnant? (I’m not ovulating rn btw- I always ovulate right after my period ends which was when I had sex)
