Pregnancy symptoms?

Hi :) are these pregnancy symptoms?

I have nausea, darker nipples, itchy nipples, inflamed glands around nipple, creamy discharge, fatigue, acne, back pain, and headaches. My cycles are irregular, they range from 30-61 days, we only had sex enough for a 28-34 day cycle, if I was having a 30 day cycle then I should’ve started my period today.
