am I pregnant?

So my period is late by 11 days now😪.. I’ve woken up these past mornings throwing up bile (stomach acid: bright yellow), every smell was making me nauseous, and I’m very sleepy at work when I’m usually the perky, bossy type.. my breast are very sore.. idk you guys is my period gonna be that late or am I pregnant? I’ve took test in the past and gotten back negatives because my period is irregular but it never skips a whole month..
