Spotting or period

This was yesterday I’m not currently bleeding but sometimes when I wipe I can tell I am. My actual period was supposed to star the 30th and I always cramp and have the runs a week before I start it’s my body preparing for my period I guess. But this time it didn’t happen I went to the bathroom around like 10pm wiped and saw brown blood but only a lil but no cramps so I’m thinking maybe it’ll flow tomorrow so it had been 4 days and it’s been like this and sometimes nun at all and I wake up in my sleep hot as ever. Could I be pregnant I’m not ok bc or anything and cycles are regular
