Should I test?

I feel like lately I’ve been having symptoms like soreness in the breasts, the worst what i think cramps, nausea, morning sickness, and I missed one day of my period. Usually I get my periods in the night or the mornings and it hasn’t happened, but my periods CAN be irregular and maybe I’m confusing the symptoms to period symptoms as I’ve never been pregnant before. Should I test already on day two? Or wait longer?
