Could I be?

So I had a period may 3-6 and another one from May 28-31, so two periods in one month. I've had unprotected sex with my SO and this month of June I haven't gotten my period. I'm currently 5 days late. I've had all the regular symptoms of my period happening but it just hasn't happened. Should I test? Or wait to see if it just shows up? Idk what to do
