Spotting Reassurance

Hi all,

Kind of overthinking now. Also a little stressed with a move as well. Probably that's why I'm spotting or starting an irregular period? This month I was also sick during my period, caught a cold. Today after intercourse I wiped and saw there was spotting that resembled old period blood. All day I was fatigued and had a headache. I'm usually very regular. My last irregular period was back in September. I guess I'm overthinking maybe could mean pregnancy?? But looking at my current cycle it doesn't seem so. Too early to test too. Also I was thinking possibly just rough sex could have resulted it. No pain during intercourse. Just always get so anxious when something is off! My projected period isn't supposed to start until next Friday
