I’m I pregnant or is my period late

Hi I’m 22years old, My period is late!! I have been very tired, sluggish, fatigue, increase hunger, bad acne migraine headaches, light airy cramping I could barely feel in my stomach and back. I have regular cycles always on time starting at day 1 - 35. My period was post to come on the 24th but it did not I have spotted on the 22 a light pink when I wipe. June 30th I spotted dark brown on my panty shield. July 1st I spotted again this time pinkish and a little more than June 30th. July 2nd I spotted heavily with some clots but it’s not a continuous flow it is off and on with bright red blood light pink and brownish more than a couple hours apart. I have never been pregnant and I have never taken any birth controls. I have taken two pregnancy test and both came back negative
