am i pregnant?

my period was supposed to start on february 8th, and it is now february 14th. i took a test about 3 days ago and it came back negative. i took plan b on december 6th, but i feel as if it shouldn’t be affecting my cycle anymore. could it be a false negative? also, my eating habits aren’t that great, so i was thinking that maybe that could be affecting my cycle.

yesterday i also started experiencing abdominal pain in the lower left quadrant of my abdomen.

i just need someone else’s opinion on the situation. thank you!
