ovulation symptoms?

Kylee • Love my husband and my cats.
According to glow I'm supposed to ovulate tomorrow, but have gotten a piosituve opk yet. I'm having some pretty intense cramping alternating between the right and left ovary, major headaches, nausea, and diarrhea. Has anyone else gotten symptoms like this during ovulation? Or possibly pregnancy? I'm thinking glow might be off by a week or so and I might've ovulated last week
