Period maybe???

So, at 9 dpo I tested - faint positive.

10dpo - faint positive

11dpo - faint positive

12dpo - faint positive

I’ve been having light cramps, headaches, light nausea and fatigue all week... today I’m at 12 dpo and the light cramps continue... sleepiness continue, but I just started “bleeding” a little. It was light red, kinda pinkish, and a light flow... the only thing is my period wasn’t expected for another 2-4 days. Is it just an early period?

Ive had 2 or 3 chemicals that I know of from December 2018 - November 2019 so at this point, that’s what I expect (though that’s not what I want) I’m just concerned. I don’t want it to be a period but I’m afraid it might be.
