So ive been having this blood for about 4 days now. My period supposed to come on the 21st

This started on the 9th and now the 13th.

My periods are usually HEAVY and this is the most I’ve been getting for the past few days - enough to dirty a tampon but no my enough to stain a pad like it normally would. I’ve had all the symptoms cramping headaches. But I’m assuming it’s still too early to test. But this is DEFF not a normal period my periods are short and heavy flow so day 1-3 heavy flow - 4th day brown dark dried out so deff not sure what’s going on.
