Symptoms 3 DPO?

I ovulated Sunday or Monday, and starting yesterday I've been having pretty moderate cramping. Never had cramping like this after ovulating. I know you don't typically start to see symptoms until a week after but I know some women have had symptoms a few days later and could just tell something was up. Just trying to gather some opinion on what you ladies think! This is our first month TTC and I'm hoping for the best, I tracked everything and we used an OPK. Thoughts? When did you start noticing differences?
