5 days missed period with major cramps 😭

Linda
Hello! I am 5 days late AF with no signs of menstrual. Usually even if I am late I will have some light pink spotting. I am also having heavy cramps and tight feeling in uterus area. Random nausea here and there but nothing major.  AF is usually on time maybe off by 2 days some months. I took 2 test and both came back negative 😞. Are the heavy cramps a sign of early pregnancy or is AF being stubborn to visit this month? Is anyone in the same boat?Â
