help ladies!!!

so my period is usually right on track, this month I'm 2 days late and I'm having PMS symptoms from hell! I never bloat or have gas, I'm never extremely tired, or have food aversions. I also don't get emotional and cry I just get mad but this month I've cried over everything. I never want to jump to conclusions and get excited about possibly being pregnant so I'm leaning more forward hormonal issues. has anyone had this happen to them? and what was it?
