i might be pregnant but idk and i’m scared someone please help

My boyfriend and i have had raw sex but not to the point where we’d be worried about cum or anything. we usually always use condoms. my period was supposed to come 6 days ago but it hasn’t but i am spotting but it’s brown with a lot of blood clots. i’m not having tender breasts nor nausea but i have been cramping, not been able to sleep and really depressed. should i be worried?
