Implantion

Hi everybody so I’m 5 days late on my cycle my cycles are not regular. But according to these apps 5 days late.. I wiped and literally had light baby pink blood and it was not a lot it was so little I’ve had a dizzy spell and I threw up so much back cramps daily ( mild ) and ovary pinch feelings… I took a test it was super super faint like almost impossible to see on a camera but I seen another pink line with frer early rapid test.. has anybody had implantion bleeding after 4/5days late on period? Could I be pregnant?
