Help. Am I pregnant or not 😬

I'm kind of spotting but it's "chunky" (sorry idk how else to word it.) but there isn't much blood and it's off and on for the last three or so days. I've only had sex once since my last period but we used protection. I'm getting antsy because the spotting started the day my period was supposed to start. Please help I'm driving myself and my boyfriend crazy. Â
