6 days late

Okay so last month my period was due on the 15th but came on the 19th. i bleed heavy for about 1 out of 5 days when normally i bleed heavy 2-3. I had a little cramping but not much . so after my period was done about 5 days later i started lightly bleeding like pink. no cramps or anything but when i wiped it would be there but not heavy in my underwear or anything . so that lasted about 5 days.

now this month my period is late 6 days and i’ve been feeling nauseous, my boobs seem to be getting bigger, my sense of smell is crazy and i’m always tired now.

should i test tomorrow since i’ll be a week late then ?
