Is this my period or something else?

I'm 2 days late and now I'm spotting. The spotting is gradually turning darker, as it has gone from white to light brown now. It was also accompanied by slight cramping. So I thought duh this is AF. But after spotting for 4-5 hours I'm now starting to feel a little blah. I'm having an on & off headache & my appetite has increased tremendously. I know this all sounds like AF, as I too agree, it's just that those random symptoms are tricking me up because increased appetite & headaches aren't common AF symptoms for me. Now the cramps are merely just waves & I don't know if I'm still spotting because I put a tampon in. Please don't judge me or lecture me about how you should only put a tampon in when your vagina is in dire need of it, my vagina goes from 0-100 real quick so one minute I'm spotting, the next minute it's the crimson tide and I don't have time to play with Ms. Vagina SO after allat, does this sound like AF (I think it does) or could I be pregnant or what?
