Am I feeling ovulation or pregnancy?

I'm right in the middle of my cycle (day 14 or so), and I'm feeling slight cramps (or maybe not even--kinds feels like weird swirling or knots in my lower belly) and I have kinda heavy white and clear discharge. I did have (protected) sex 2 weeks ago before my period started, so I'm wondering if our condom was ineffective and I'm pregnant, or could this be due to me ovulating?
