Is this the start of my period?

My period was supposed to start anywhere from tomorrow (Nov 4th-Nov 6th), I had unprotected sex when I was ovulating, this is only there when I wipe and there hasn’t been anything on a pad except a little tiny spot. Has been happening for hours now, my boobs were super sore but they aren’t really now, they are kinda sore but not as bad. And I keep having horrible mood swings
