Nausea & Feeling Ovulation

Is nausea the day of and/or after ovulation normal? I'm wondering if it has anything to do with hormone fluctuations. I think I actually felt ovulation happen this month. Had positive opk, then the next night I woke up in the middle of the night, took my temp (was still low), went pee, got back in bed and had a little trouble falling back asleep, had some mild right side belly cramping, went to sleep, woke up a few hours later, temp'd again and was .4 degrees higher than it had been and has stayed that way. Anyway, the next morning I felt nauseous and wasn't sure if it was because I ovulated.
