Should I wait to test?

I'll start off by saying we aren't trying and were actively preventing pregnancy but I forgot a pill or 2 and I think one of those nights we forgot a condom. I didn't have any early symptoms with my son and same thing now. I just kind of "feel" pregnant. My period is due within 3 days and I kind of want to test to put my mind at ease. Should I just wait it out or test anyway?
