chemical? AF early ? what is going on?

last night i went to the bathroom, wiped and had very light pink coloration on the TP, which i thought it to be implantation bleeding. fast forward to 2:45a this morning - id been up already for almost 3 hours, cramping and significantly more nauseous than i’d been the second half of yesterday. i took a test and got what looked like it could be a veeeeeeeeeery faint positive?

fast forward to 6:30a, the vomiting started, and much darker colored blood and heavier clotting (not as much as my typical periods though).

what is going on? i shouldn’t be getting my period for another 3 days, and my periods never shy from they’re expected date.

if it is a chemical, this will be #2, #1 was only back in november 😔
