Mastitis or pregnancy?

I’m currently breastfeeding and last night I had a sore boob so thinking it was a clogged duct I massaged it but it never felt better just a bruised sore feeling. I started having fever shakes, nausea, dizziness, cramps and bloating. I don’t know if I ovulated this month since we just got off the pill to try again. I’m wondering if this sounds like mastitis or pregnancy to any of the moms who have had either while breastfeeding. Thanks!
