2 days late

So it’s been almost 4 weeks that I had unprotected sex where there was ejaculation. I forgot 2 pills consecutively that night and the next. I recently was traveling to South Korea and was very nauseous and when I got back home I realized I missed one pill due to the time difference. I was spotting lightly and then stopped. I finished my pills on Tuesday and now I haven’t gotten my period, there’s just some brown/old blood coming out. Is this normal, should I wait till tomorrow to see if my period actually comes or should I take a test? Usually by the next day after my pack I have my period right away that’s why I’m a little worried
