Im almost 2 and a half weeks late on my period. ever since i started having sex 6 months ago my period happen the day of oe a couple of days after the day it stopped the month before. Ive taken 5 pregnancy tests and they were all negative. Ive had little to nothing symptoms other than being tired and small cramping ive been having these past two days. Also my breasts seem a lot firmer but they dont hurt at all. I cant tell if im pregnant or just skipped a period
