Is it possible I ovulated early?

So my period ended on June 13th (only lasted 5 days). A week later I had light spotting (light pink color) but only noticed when I wiped after I peed that lasted a few days. My ovulation day was predicted to be June 28th. I’ve always had irregular periods. Now today I’m having a terrible migraine, bloating, slight cramps, and some nausea.

Is it possible that I ovulated early and this could be early pregnancy symptoms? We aren’t actively trying, never use protection, and wouldn’t be mad if something happened.
