Im so confused

My nipples hurt so bad it's been going on for 3 months, I thought it was just a period symptom but it hasn't gone away. I've been extremely nauseous, with bad head aches, dizziness and heart burn. My period in October was 3 days late and it only lasted 2 1/2 period is never late and the blood wasn't the same this time. My boons hurt as I'm writing this, should I take a test or wait for my next period?
